Question

Two complementary angles differ by 20.The larger angle is

Answer 1

Step-by-step explanation:

Complementary angle = 90°

Let the larger angle be X:

X + Y = 90°

Value of Y is = 20°

X = Y+ 20

Y = (X + 20) X

2X = 90 - 20°

2X = 70°

X = 70/2

X = 35

Now Larger angle:

X = 35 + 20°

X = 55°
