Answer: 45

Step-by-step explanation:

59 + 76= 135

180-135= 45

Answer:

m∠1 = 45 degrees

Step-by-step 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
