Question

In a right angled triangle, one of the complementary angles is double the other. What are these angles?​

Answer 1

Answer:

let a,b,c be the angles

and triangle PQR IS A RIGHT ANGLE TRIANGLE AT b .

so remaining

a+c =90°

now a=2c

a+c =90°

2c+c=90

3c=90

c=90/3

c=30 °

now

a=2c

a=2×30

a=60°
