Question

Find the supplement of the angle 4/5 of 90 degree

Answer 1

given angle= 4/5×90°=>4×18=>72°
Now, we had to find the supplement of 72° :-
supplementary angle=180°
supplement of 72° =(180-72)°=>108°
Hence the required angle is 108°

Answer 2

Answer:

The supplementary angle is 108°  

Step-by-step explanation:

Given the angle 90°

we have to find the supplementary of four-fifth angle of 90°

$\frac{4}{5}\text{ of 90°}=\frac{4}{5}\times 90=72^{\circ}$

We have to find the supplementary angle of 72°

Let the supplementary angle=x

As supplementary angle adds up to 180°

⇒ x°+72°=180°

x°=180°-72°=108°

Hence, the supplementary angle is 108°
