Question

b) Three angles of a triangle are x° (x+10°) and 70°. Find the two angles of the triangle​

Answer 1

Solution:

We know, sum of angles of a triangle = 180°

∴ x + (x + 10) + 70 = 180

⇒ x + x + 10 + 70 = 180

⇒ 2x + 80 = 180

⇒ 2x = 180 - 80 = 100

⇒ x = 100/5 = 50

∴ the angles are:

∠1 = x° = 50°

∠2 = (x + 10)° = (50 + 10)° = 60°

∠3 = 70°

Answer:

The unknown angles are 50° and 60°.
