Question

Find the unknown lettered angles​

Answer 1

Answer:

35,60,85

Step-by-step explanation:

as there is straight angle

other angle = 180°-95° = 85°

sum of all angles in triangle = 180°

x + (2x-10)+85° = 180°

3x-10° = 180°-85°

3x-10 = 95°

3x = 95°+10°

x = 105°/3

x = 35°

1st angle = x = 35°

2nd angle = 2x-10 = 2 X 35 -10 = 60°

3rd angle = 85°

Answer 2

Answer:

1. 180 - 50 + 70 = 180 - 120 =60
