Question

Can someone find the missing measurement?

Answer 1

The missing measurement is equal to 141°.

Explanation:

What we know:

- There are two angles

- They both sit on a straight line (recall that a straight line equals 180°)

- One of the angles' measurements is unknown

----> In this case, we can take the 39° and subtract it from 180° to figure out the degrees of the unknown measurement.

So, 180° - 39° = 141°

Therefore, the unknown measurement is equal to 141°.

Hope this helps. <3.

Answer 2

Given this line is supplementary, we know both angles add up to 180°. We can set up an equation:

39 + x = 180

180 - 39 = 141°

Hence, the missing measurement is 141°.
