Question

∠ 1 and angle∠2 are complementary angles. The measure of angle∠1 is 33°. The measure of angle∠2 is 3x°. Find the value of x. (Figure below not drawn to scale)

Answer 1

Complementary angles add up to 90 degrees.
m < 1 + m < 2 = 90
33 + 3x = 90
3x = 90 - 33
3x = 57
x = 19

Answer 2

The value of x is 19

The sum of complementary angles is 90.

Now we have ;

Angle 1 + Angle 2 = 90

33 + 3x = 90

3x = 90 - 33

3x = 57

x = 19

The value of x is 19
