Find the missing angle measure.

1.)35°
2.)40°
3.)35°
4.)45°
5.)50°

1) 35

Step-by-step explanation:

1. First, you have to realize that a straight line is 180 degrees.

Why is this important to know? Well you know that all angles of a triangle added up together HAS to equal 180, it'll be a straight line

2. Add 40 and 105, this gives you 145.

3. Subtract 145 from 180, and you should get 35, which is x.

You can check this by adding 40, 105, and 35 together.
