(ii) An angle is 30° less than three times its complement. Find the angle.
Find the value of x.

Answer 1

Answer:

(i) As the numbers given are supplementary angles. So,

4x+28+x-8=180°

5x+20=180°

5x=160°

x=160°/5= 32°

(ii) Let angle be x

x+(30°+3x)=90° [Linear Pair]

x+3x=90°-30°

4x=60°

x=60°/4= 15°

Therefore, angle is 15° and

value of x is 15°
