Find the missing angle.

(look at the picture)

Answer 1

m∠1 = 45 degrees

Explanation:

All triangles have the interior angle of 180

to find the missing angle, take the known angles and add them together:

76 + 59 = 135

then take the sum and subtract it from 180:

180 - 135 = 45

Answer 2

Answer: 45

Explanation:

59 + 76= 135

180-135= 45
