Question

Two supplementary angles are in the ratio of 4:5 fingers the angles

Answer 1

Step-by-step explanation:

Let the angles be 4x and 5x

Angles are supplementary

∴4x+5x=180

∘

⇒9x=180

∘

⇒x=20

∘

So the angles are

4×20

∘

=80

∘

5×20

∘

=100

∘

Answer 2

Answer:

let the angles be 4x & 5x ;

; given ;

4x + 5x = 180° [ supplementary angles ]

9x = 180

=> x = 180/9

{ x = 20 }

so the angles are :-

4x = 4(20) = 80°

5x = 5(20) = 100 °

Therefore , 80 ° & 100° are the angles
