1) In the diagram, l || m. If the measure of angle 3 is 120 find the measure of the following angles
a) angle 4
b) angle 6
c) angle 8
Answer:
a) angle 4 = 60°
b) angle 6 = 120°
c) angle 8 = 60°
Step-by-step explanation:
a) angle 4 =
angle 3 and angle 4 are on the straight angle and they are both equal 180°angle 3 = 120
angle 4 = 180 - 120 = 60
a) angle 4 = 60°b) angle 6 =
angle 6 = angle 2 and angle 2 = 120°b) angle 6 = 120°c) angle 8 =
angle 6 and angle 8 are on the straight angle and they are both equal 180°angle 8 = 180 - 120 = 60
angle 8 = angle 4 and angle 4 = 60°c) angle 8 = 60°Angles 4, 6, and 8 in the given parallel line scenario would all measure 120 degrees because they are alternate interior, corresponding, and vertical angles to angle 3 respectively.
Explanation:When dealing with parallel lines and transversals in geometry, certain angles have specific relationships. Given that lines l and m are parallel and angle 3 measures 120 degrees, we can deduce the following:
Angle 4: This angle is an alternate interior angle to angle 3. Therefore, angle 4 will also measure 120 degrees because alternate interior angles are equal when two lines are parallel.Angle 6: Since angles 3 and 6 form a pair of corresponding angles and lines l and m are parallel, angle 6 is also 120 degrees.Angle 8: Angle 8 is a vertical angle to angle 3. Vertical angles are always congruent, hence angle 8 equals 120 degrees.Remember that in parallel line angle relationships, alternate interior, corresponding, and vertical angles provide a dependable method to find missing angle measures.

ΔDEF and ΔXYZ are similar isosceles triangles. What is the measure of X?
75°
105°
60°
30°
Answer: Angle X = 30
Step-by-step explanation: First and foremost, we should recognize that an isosceles triangle has two sides equal and the two angles subtended by the two equal sides are also equal in measurement.
This means. In the diagram on the left, line DE = line DF and that is 10cm.
The similar angles are the ones subtended by the lines identified as being equal, that is
Angle E = angle F and that is 75. If both angles measure a combined total of 150 the third angle can be derived simply as
180 - (75+ 75)
{Sum of angles in a triangle = 180}
180 - (150)
= 30
Therefore angle D = 30.
However having been given in the question that both triangles are similar and are isosceles, then
Angle D = Angle X and that is 30

Point A is located at (3,-6) and point A is located at (1-2). What is the scale factor?
Answer:
The scale factor is 3.
Step-by-step explanation:
Let the origin O(0,0) is the reference point and the coordinates of the point A are given by (3,-6).
Therefore, the distance OA is given by [tex]\sqrt{(3 - 0)^{2} + (- 6 - 0)^{2}} = 3\sqrt{5}[/tex] units.
Again, the coordinates of point A' are (1,-2).
Therefore, the distance OA' is given by [tex]\sqrt{(1 - 0)^{2} + (- 2 - 0)^{2}} = \sqrt{5}[/tex] units.
Hence, the scale factor is [tex]\frac{OA}{OA'} = \frac{3\sqrt{5} }{\sqrt{5}} = 3[/tex]. (Answer)

x(y + z - 3 squared)
After evaluating the expression with the given values for x, y, and z by following the order of operations, the final result of the expression is 28.
Explanation:To evaluate the expression given x=4, y=9, and z=7, we follow the order of operations, which means we perform the operations inside the parentheses first before multiplying by x.
First, calculate the value inside the parentheses as follows:
y + z - 3 squared
= 9 + 7 - 32
= 9 + 7 - 9
= 16 - 9
= 7
Now, multiply this result by x:
x(y + z - 3 squared)
= 4(7)
= 28
So, the evaluated expression equals 28.

Annual student fees at the University of California rose from about $4,000 in the year 2000 to about $12,000 in 2010. Find the percent increase.
Answer: 200%
Step-by-step explanation:
We are asked to find the percent increase in student fees. The amount of increase in student fees is given by
final amount − initial amount = increase
12,000 − 4,000 = 8,000
We can now find the percent increase by finding what percent the amount of increase is of the initial amount. In other words, we want to find what percent 8,000 is ... of 4,000.
Let p be the percent. The question can be translated into an equation.
8,000 {is} {what percent} {of} 4,000
8,000 {=} { P } {x} 4,000
To solve for p, we can now divide each side by 4,000 and simplify.
8,000 = 4,000p
p=2
To convert p to a percent, multiply 2 by 100.
2 x 100
=200%
It follows that the percent increase in student fees was 200%.
Answer:
200%
Step-by-step explanation:
Find the amount of change.
12,000−4,000=8,000
Find the percent.
Change is what percent of the original amount?
Let p= the percent.
8,000 is what percent of 4,000?
Translate to an equation and simplify.
8,000 = p⋅ 4,000=
8,000 = 4,000p
Divide both sides by 4,000 and change to percent form.
2=p
200%=p

Determine the measure of the missing angles. Show your work! Be ready to discuss your answer.
For a.
Since there are already two angles given for the triangle, we can measure the last angle using this formula:
90 + 55 + a = 180
Now solve for "a".
90 + 55 + a = 180
145 + a = 180
a = 180 - 145
a = 35°
For b.
From the picture above, the two triangle's tip are touching and having to form vertical angles. This means that the angles are congruent to each other.
Now that we have two angles in the second triangle(35 and 120), we can use the same formula:
35 + 120 + b = 180
Now solve for "b":
35 + 120 + b = 180
155 + b = 180
b = 180 - 155
b = 25°
Answer:
a = 35 b = 25
Step-by-step explanation:
Triangles always add up to 180 degrees. Knowing this we can first solve the triangle with the right angle.
55 + 90 + a = 180
Before we solve this, keep in mind that the reflective property will be used on angle a, giving the answer to the third angle in the second triangle.
145 + a = 180
-145 -145
a = 35
Now that we have a solved use the reflective property to get it on the second triangle.
120 + 35 + b = 180
155 + b = 180
-155 -155
b = 25
There you have your two angles.
Hope this helped you out.
