Question

ZA and ZB are complemantry angle such that mZA =x+10 and mZB 2x-40 then mZA=?​

Answer 1

Answer:

mzA = 50°

Step-by-step explanation:

we know that sum of complementary angles is 90°.

so, mZA + mZB = 90°

=> x+10 + 2x-40 = 90°

3x = 90+30

3x = 120°

x = 120°/3

x = 40°

mZA = 40°+10°

mZA = 50°
