Answer 1

Answer:

According to exterior angle property of∆ sum of opposite angle of ∆ is equal to exterior angle.

i) x = 70°+50° = 120°

ii) x= 65°+45° = 110°

iii) x= 30°+40° = 70°

iv) x= 60°+60° = 120°

v) x= 50°+50° = 100°

vi) x= 30°+60° = 90°

Answer 2

Answer:

1. 50°+70°=120°

2. 65°+45°= 110°

3. 30°+40°= 70°

4. 60°+60°= 120°

5. 50°+50°= 100°

6.30°+60°= 90°

Step-by-step explanation:

you think why he is adding?

Because the interior angles of a triangle add to 180°, and angles c+d also add to 180°:

1. the interior angles of a triangle add to 180°:a + b + c = 180°

2. Angles c and d make a straight angle, which is 180°:d + c = 180°

2. So d + c equals a + b + c:d + c = a + b + c.

Subtract c from both sides:d = a + b.
