Question

Two supplementary angles are in the artio 7 : 11 . Find the angles

Answer 1

Answer:

Let angles are 7x and 11x.

As these are suplementary angle

Sum of angle =90 degree

7x+11x=180

18x=180

x=10

Hence angles are, 70 and 110 degree

Answer 2

Step-by-step explanation:

solution :let the two angles be 7x and 11x.

now 7x+11x=180(supplementary angles)

thus, 18x=180

so, x=180/18=10
