Question

If (3x-15°) and (x+5) are complementary angles. Find the anges

Answer 1

Here is your answer.....

_______________________________

✔✔When the sum of two angles= 90°

we call these angles as complementary angles.

(3x-15°) + (x+5°)= 90°

4x-10° =90°

4x= 100°

x= 100/4

x= 25°

Answer 2

Answer:

the required angles are 60°and 30°

Step-by-step explanation:

We know that,

the angles whose sum is equal to 90° are called complementary angles.

So,

The sum of the given angles must be equal to 90°.

=> ( 3x - 15° ) + ( x + 5 ) = 90°

=> ( 3x + x ) + ( 5 - 15 ) = 90°

=> 4x - 10° = 90°

Adding 10° on both L.H.S and R.H.S

=> 4x = 100°

=> x = 100°/4

=> x = 25°

So, the value of

x = 25°

Hence, the required angles are

1. 3 × 25° - 15° = 75° - 15° = 60°

2. 25° + 5° = 30°
