Question

Which equation can be solved to find x, the measure of JK in the diagram below?

Answer 1

The answer is A

Explanation:

I just did the test

Answer 2

A.
`(1)/(2) (120\degree-x)=48`

Explanation:

By the amgle-chord-secant theorems.

`m\angle L=(1)/(2) (m\overline{MN}-m\overline{JK})`

When we substitute the given measures we obtain:

`48\degree=(1)/(2) (120\degree-x)`

This is the same as the first option.

Therefore the correct answer is A
