Question

Anybody know how to do this ?

Answer 1

Hey there!

In this diagram, x is the exterior angle of the triangle.

The measurement of the exterior angle is the sum of the other two interior angles (this formula only works for triangles).

The two interior angles have measurements of 50 degrees and 93 degrees.

We can just add those together to get the value of x.

$x=50+93=143$

The measurement of x is 143 degrees.

Have an awesome day! :)

Hey there!

The interior angles of a triangle equal 180.

We can use this and the measures of the angles we are given to find the missing interior angle.

50+93=143

180-143=37

Since the missing angle (37) and angle x are supplementary, they add up to 180 as well.

37 + x = 180

180 - 37 = 143

x = 143

Hope this helps!
