Question

two complementary angle are in the ratio 11:7 find the angle​

Answer 1

Step-by-step explanation:

Let x be common multiple in ratio of angles. Sum of supplementary angles = 180°. Now angles are 7x = 70°. 11x = 110°

Answer 2

LET THE ANGLES BE X & Y

AS THE ANGLES ARE COMPLEMENTARY

HENCE

X+Y=90°. {1}

NOW GIVEN

X/Y=11/7

X=(11/7)×Y

PUT THIS VALUE IN EQUATION 1

HENCE

11/7Y+Y=90

18/7Y=90

Y=35°

X=90-Y=90-35=55°
