Question

If two angle of a triangle are 52° and 43°, then the third angle is equal to * a) 30° b) 85° c) 20° d) 10°​

Answer 1

Answer:

opt b 85 degree

Step-by-step explanation:

52+43+×=180

95+×=180

x=180-95

×=85

Answer 2

Answer:

c.85°

Step-by-step explanation:

It is given us that-

The 2 angles of a triangle is 52° and 43°

We know that the sum of the angles of a triangle is 180°.

So (1st angle +2nd angle) + 3rd angle = 180°

=(52°+ 43°) + 3rd angle =180°

= 95° + 3rd angle = 180°

= 3rd angle = 180° - 95°

= 3rd angle = 85°

So the third angle measures 85°.

Hope you understand clearly..
