Answer:
135°
Step-by-step explanation:
a supplementary angle is equal to 180°. since you already have the measure of ZA, all you need to do is subtract 45°, the measure of ZA, from 180°, the total measure of a supplementary angle, in order to figure out the measure of ZB.
180 - 45 = 135, therefore the measure of ZB = 135°.

Answer:

Step-by-step explanation:
h + 20 =35 -4h
h + 4h = 35 -20 ( so subtract 4h on both side and subtract 20 on both side )
5h=15
h = 15/5 ( so divide 5 on both side)
h=3
