Question

Suppose that COP and TOD are vertical angles. MCOP = 11x-17 and mTOD =9x+11

Answer 1

`x = 14`

Explanation:

Given

`COP = 11x- 17`

`TOD = 9x + 11`

Required

Determine x

Since COP and TOD are vertical angles, we have:

`COP = TOD`

`11x - 17 = 9x + 11`

Collect Like Terms

`11x-9x = 11+17`

`2x = 28`

`x = 14`
