Answer:
∠ZB = 54°
Step-by-step explanation:
Given:
Pair of complementary angles
∠ZA = (2x + 10)° and m
∠ZB = (3x + 15)
Find:
Measure of ∠ZB
Computation:
complementary angles
a + b = 90°
∠ZA + ∠ZB = 90°
(2x + 10) + (3x + 15) = 90
5x + 25 = 90
x = 13
So,
∠ZB = (3x + 15)
∠ZB = 13(3) + 15
∠ZB = 54°
I wanna say its b)1 but im not 100% sure. if its wrong im sorry
m∠1=31
m∠2=59
m∠3=90
m∠4=31
m∠5=90
hope this helps brainliest please!
The other end point would be (5,-11)
