Question

B.
А.
5. Angles A and B are complements of each other. If ZA = (x - 20)° and ZB = (x - 30)º,
find the measure of both the angles.​

Answer 1

Answer:

Given that ;

Angles A and B are complements

ZA = ( x - 20 )°

ZB = ( x - 30 )°

Sum of two complementary angles = 90°

( x - 20 )° + ( x - 30 )° = 90°

2x° - 50° = 90°

2x° = 90° + 50°

2x° = 140

x° = 140 / 2

x° = 70

Hence ;

Measures of Angles ,

( x - 20 )° = 70 - 20 = 50°

( x - 30 )° = 70 - 30 = 40°
