Question

My friend needs help please help her

Answer 1

Answer:

• Given Below.

Explanation:

All angles in a triangle sum up to 180°

• third angle = 180° - first angle - second angle

1)

180° - 24° - 25 = 131°

2)

180° - 40° - 50° = 90°

3)

180° - 60° - 60° = 60°

4)

180° - 42° - 66° = 72°

Answer 2

Answer:

131°

90°

60°

72°

Step-by-step explanation:

Sum of the interior angles of a triangle = 180°

Therefore, to find the missing angle, simply subtract the known values from 180°

180 - 24 - 25 = 131°

180 - 40 - 50 = 90°

180 - 60 - 60 = 60°

180 - 42 - 66 = 72°
