Answer:
ZB = 54
Step-by-step explanation:
Complementary angles add to 90 degrees
ZA + ZB = 90
x-15 + x+3 = 90
Combine like terms
2x-12 =90
Add 12 to each side
2x-12+12 = 90+12
2x = 102
Divide by 2
2x/2 = 102/2
x = 51
We want to find the measure of ZB
ZB = x+3
ZB = 51+3
Answer: (x-3)/(4)=(x)/(10)
X=5
Hope this helps!
Thanks!

y = 5
y = mx + b
5 = 6m + b
5 = 3m + b
Take the first minus twice the second.
-5 = - b
b = 5
Substitute back to calculate m.
5 = 6m + 5
6m = 0
m = 0
