What is the measure of
Nastasia [14]

Answer:

70

Step-by-step explanation:

The sum of the angles of a triangle should always add up to 180 degrees.

In this problem, they have given us 2 angle measures of the triangle - 40 degrees and 70 degrees. To figure out the third angle, we simply need to figure out how many more degrees we need for reaching the 180 degrees.

I'm just going to do some simple math:

40 + 70 = 110 (sum of the 2 angles)

180 - 110 = 70 (subtracting 180 by the sum of the 2 angles)
