Question

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

Answer 1

Answer:

3x-15+x+5=90

4x=90+10

4x=100

x=25

3x-15=3(25)-15=75-15=60

x+5=25+5=30

Answer 2

Step-by-step explanation:

3x-15+x+5=90°

4x-10=90°

4x=90+10

4x=100

x=100/5

x=25

put it in

3×25-15

=75-15

=60°

25+5

=30°

So,these angle are 60°,30°.
