Question

If the two complementary angles measure (5x-3)° and (8x-2)°, then the value of 5x is

Please answer fast

Answer 1

Complementary angles equals 90 degrees
So,
(5x-3) + (8x-2) =90
5x + 8x -3-2 = 90
5x + 8x -5 = 90
Adding 5 to both sides
5x + 8x -5+5=90+5
5x +8x =95
Subtracting 8x from both sides
5x +8x -8x = 95-8x
5x = 95 - 8x

Answer 2

The value of 5x = 36.535

Given:

If the two complementary angles measure (5x-3)° and (8x-2)°

To find:

The value of 5x is

Solution:

Complementary angles:

• The pair of angle whose sum will equal 90° are called as Complementary angles.
• The complementary angle of an angle A will be equals to (90°-A)

Given (5x-3)° and (8x-2)° are two complementary angles

⇒ (5x-3)° + (8x-2)° = 90°

⇒ 13x - 5 = 90

⇒ 13x = 95

⇒ x = 7.307

5x = 5(7.307) = 36.535

The value of 5x = 36.535
