Question

If (3x-15) and (x-5) are complementary angel find the angel

Answer 1

hope this helps u

Two Angles are Complementary when they add up to 90 degrees

so

3x-15+x-5=90

4x-20=90

4x=90+20

4x=110

x= 110/4

x=27.5

3x-15=3*27.5-15=67.5

x-5=27.5-5=22.5

verification

3x-15+x-5=90

67.5+22.5=90

90=90

Answer 2

Answer:

Step-by-step explanation:

(3x - 15) +(x - 5) = 90 (complementary angles add up to 90 degree)

3x - 15 + x - 5 = 90

4x - 20 = 90

4x = 90 + 20

4x = 110

X = 27.5

Angle 1 = 3 x - 15

82.5 - 15 = 67.5

Angle 2 = x - 5

27.5 - 5 = 22.5
