Question

the angles x-10and 2x+5are complementary to each other.Find the value of x​

Answer 1

If the two angles are complementary, then:

2x+5 + x-10 = 90 degrees

Solving the equation one gets:

3x - 5 = 90

3x = 95

x = 95/3

Answer 2

Answer:

x - 10 + 2x + 5 = 90 ( complementary angles have sum = 90 )

=> 3x - 5 = 90

=> 3x = 95

=> x = 95/3

x - 10 = 35/3

2x + 5 = 205/3
