Question

If (3x - 15°) and (x+5°) are
complimentary angles, find the
angles.
​

Answer 1

Answer:

sum of complementary Angles=90°

Here,the angles are 3x-15,x+5

3x-15+(x+5)=90

4x-10=90

4x=100

x=100÷4=25

there fore,the angles are

3(25)-15=75-15=60;25+5=30

there fore, the angles are 60°,30°

Hope this is helpful

Answer 2

Answer:

60° and 30°

Step-by-step explanation:

We know that the sum of any two complimentary angles is 90°.

Therefore, (3x-15) + (x+5)= 90

= 3x-15 + x+5 = 90

= 4x-10= 90

= x = 100/4 = 25

Putting the value of x in (3x-15°) and (x+ 5°), we get

(3×25°-15°)= 75°-15°= 60°,

and,. (x + 5°)= 25+5°=30°.

Hence, 60° and 30° are the two required angles.
