Question

Two adjacent angles are in the ratio 5:3 and they together form an angle 128 degree. find these angles.​

Answer 1

Answer:

Sum of two adjacent angles = 128°

and ratio between them = 5:3

Let first and = 5x

Then second angle = 3x

5x+3x=128°

⇒8x=128°

⇒x=16°

First angle = 5x=5∗16°

=80°

and second angle = 3x=3∗16°

=48°
