Question

If an angle (2x-10) and (x-5) are complementary angle ,find x

Answer 1

If both are complementary, then:

2x-10+x-5 = 90

3x-15 = 90

3x = 90 +15

3x = 105

Therefore, x = 105/3

x = 35 degrees.

supplement of x is,

 180-35 = 145 degrees
Therefore the value of x is 35 degrees.

Therefore the supplement of x is 145 degrees.
