Question

ZA and ZB are supplementary angles. If m A = (7x + 10º and mZB = (7x – 26), then find the measure of ZA.

Answer 1

ZA and ZB are supplementary angles. If m A = (7x + 10º and m

ZB = (7x – 26), then find the measure of ZA.

we know that

If two angles are supplementary, then tier sum is equal to 180 degrees

so

substitute the given values

7x+10+7x-26=180

14x=180+16

14x=196

x=14

FInd the measure of angle A
