You need to use the Triangle Sum Theorem where the sum of the three interior angles in a triangle is always 180 degrees.

So, we were given two angle measurements, and with that we can find x so that it’s equal to 180:

180 - (70 + 35) =
180 - 105 =
75 degrees

Hope this helps :)

The answer is A.75°

The sum of all the angles of a triangle is 180°

75+35+x = 180.

x = 180-75-35

x = 75

What is a triangle and explain it?

A triangle is a three-sided polygon, which has three vertices. The three sides are connected with each other end to end at a point, which forms the angles of the triangle.

The sum of all three angles of the triangle is equal to 180 degrees.

Why triangle sum is 180?

The angles of a triangle always add up to 1800 degrees because one exterior angle of the triangle is equal to the sum of the other two angles in the triangle. When all the angles are added up, the sum obtained should be 180 degrees.
