Question

two angles are in ratio 4 ratio 5 find the angle if they are supplementary to each other​

Answer 1

Answer:

4/9×100=80

5/9×100=100

Answer 2

Given :

• Ratio is 4:5 and the angles are supplement to each other.

To find :

• The angles.

According to the question,

Let the angle be 4x and 5x

And supplement angle is 180°

→ 4x + 5x = 180°

→ 9x = 180°

→ x = 180° ÷ 9

.°. x = 20°

_____________....

Value of 4x

→ 4x

→ 4 × 20°

→ 80°

_____________....

Value of 5x

→ 5x

→ 5 × 20°

→ 100°

So,the angles are 80° and 100°...

_______...

Verification :

→ 4x + 5x = 180°

Putting the value of x

→ 4 × 20° + 5 × 20° = 180°

→ 80° + 100° = 180°

→ 180° = 180°

.°. L.H.S = R.H.S

Hence,Verified...
