It’s 20 I believe. All together it should be 160 so you add 118 and 22 to get 140. Then subtract that from 160 and you get 20.

The angles in the diagram are supplementary

Two Angles are Supplementary when they add up to 180 degrees. Notice that together they make a straight angle. But the angles don't have to be together.

What is the midpoint of the segment shown below? (5,4) (5,-3)

Monica [59]

The midpoint is (5, ¹/₂).

<h3>Further explanation</h3>

The midpoint is the coordinates of a point right in the middle of a line segment or two endpoints.

The Midpoint Formula $\boxed{\boxed{ \ M = \bigg( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \bigg) \ }}$

So, abscissa and ordinate of the midpoint are the averages of both endpoints. i.e., (x₁, y₁) and (x₂, y₂).

Given (x₁, y₁) = (5, 4) and (x₂, y₂) = (5, -3).

Let's calculate the midpoint.

$\boxed{ \ M = \bigg( \frac{5 + 5}{2}, \frac{4 + (-3)}{2} \bigg) \ }$

$\boxed{ \ M = \bigg( \frac{10}{2}, \frac{1}{2} \bigg) \ }$

$\boxed{ \ M = \bigg( 5, \frac{1}{2} \bigg) \ }$

We get the midpoint between the two endpoints, that is, (5, ¹ / ₂).
