Question

Find the measure of each unknown angle​

Answer 1

Answer:

1. 55 degrees, 2. 316 degrees

Step-by-step explanation:

When it shows interior angles on a triangle it adds up to 180 degrees

When it shows exterior angles on a triangle it adds up to 360 degrees

1. ? = 55 degrees

85 + 40 = 125

180 - 125 = 55

2. ? = 316 degrees

Inside of triangle:

14 + 30 = 44

180 - 44 = 136 degrees

Exterior of triangle:

360 - 14 = 346 degrees

360 - 30 = 330 degrees

360 - 44 = 316 degrees

Answer 2

. The sum of angels in the triangle must be 180
Therefore
1) 180 - (40+85)= 55
2)180-(14+30)= 136
