Question

Find the measure of the missing angle using the triangle angle sum theorm.

Answer 1

20 degrees, because 70 degrees+ 90 degrees (what’s given) = 160 degrees. And then the entire sum of a triangle all the degrees always = 180, so 180-160= 20!

Answer 2

20 degrees

Explanation:

One angle is 70 degrees and the other is 90. Angles of a triangle add up to 180. 180 - 70 - 90 = 20. The final angle is 20 degrees.
