1) corresponding pair <4 and <12
answer is a
2)
<2 = 133 (corresponding)
<2 = <5 = 133 (vertical angles)
answer a . 133
180 - ( 10x -3) is your answer
Answer:
NOTES
Step-by-step explanation:
A = -11
B= -12
This is because of how calculations work in negatives. Because they are both negative they work similarly to addition
Answer:
Step-by-step explanation:
Remark
The angles are marked as alternate interior angles. To be parallel, they must be equal. In other words x - 20 must equal 52. That's all you have to do. Just equate the 2 givens and solve.
Givens
x - 20 is one angle
52 is the other.
Solution
x - 20 = 52 Add 20 to both sides.
x - 20 + 20 = 52 +20 Combine
x = 72
