40°

Step-by-step explanation:

According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.

So with this, you need to add 70° and 70°.

You get 140°

Then to find the last angle, you will subtract the 140° by 180°.

180°-140° = 40°

Hope this helped! :)

Step-by-step explanation:

First you add 70 and 70 together to get 140 then minus it by 180.

Then you will get 40 degrees as your answer.
