Question

two adjacent angles are in the ratio 5:3 and they together form angle of 128° find these angles

Answer 1

Hey mate !!!

Answer :-

Let the angles be 5x ,3x .

Sum = 128 degrees.

=> 5x + 3x = 128 degrees

=> 8x = 128 degrees

=> x = 128/8

=> x = 16

Hence the angles are :-

5(16) = 80 degrees and

3(16) = 48 degrees.

Hope it helps !

Answer 2

let the adjacent angles be 5A and 3A,

then according to the question, we have


5A+3A=128°,


8A=128°,

then


A=128°/8,


A=16°,


therefore

first angle =5×16°=80°,

second angle =3×16°=48°
