Question

Find the missing measure in the triangle below.

Answer 1

40 degrees

Explanation:

All measures in an angle add up to 180 degrees. So since here you have the measures 63 and 77, you would add both of those up and subtract that from 180, and the remainder would be your answer.

So,

63 + 77 = 140

180 - 140 = 40 degrees

Answer 2

C

Explanation:

To find x take 180 and subtract 63 and 77
