Question

Two supplementry angles are in the ratio 7:8 find the angle​

Answer 1

Answer:

sum of the angeles =180°

ratio=7 : 8

one angle=7×180/(7+8)°=7×180/15°=7×12°=84°

another angle is 8×180/(7+8)°=8×12°=96°

Answer 2

Step-by-step explanation:

let the ratios be in the form of variable.

that is in the form of 7x+8x.

because they are supplementary angle the sum of both angles must be equal to 180 degrees.

so,

7x+8x=180

15x= 180

x=180/15

x=12 degrees.

put the value of x.

7*12= 84

8*12=96

so the solution is 84 and 96 degrees
