Answer:
x = 15
Step-by-step explanation:
These angles are supplementary so you'd set up an equation like 3x -15 +150 = 180 then solve for x from there.
Answer:
The answer is 1 and 4
Step-by-step explanation:
.25 x 4y = Y
36 divided by 4 = 9
Angles 7, 6, 3, 2 are all vertical angles, which mean they are congruent (equal)
so if angle 7 is 115° so are 6, 3, and 2
so the measure of angle 2 is 115°
The correct answer is x = 20
Parallel lines have the same slope. So the slope of the other line =2/7
