Answer:
x = 106º
Step-by-step explanation:
The interior angles of a triangle add up to 180º.
First let's find the third interior angle.
We already have: 37º & 69º.
Add them together.
= 106º
To find our third angle, subtract this value from 180º.
180 - 106 = 74º
This is our third interior angle.
x and 74º are supplementary angles, meaning they add up to 180º. This is because they lie on the same straight line and are divided by a single line which they share.
To find x, subtract 74 from 180.
180 - 74 = 106
x = 106º
This is your answer.
Hope this helps!
