Question

The complementary and supplementary angles of an angle are in the ratio 2:5 respectively. The measure of that angle is

Answer 1

Answer:

30

Step-by-step explanation:

Let the angle be y

Let the complementary & supplementary angles be 2x & 5x respectively .

5x + y = 180

2x + y = 90

------------------

3x = 90

x = 30

y = 90-2x = 90-60 =30
