Question

three angles of a triangle are x -10 degree X + 20 degree, 2 x-30 degree. find each angle​

Answer 1

Answer:

The angles are 40, 70, 70.

Step-by-step explanation:

Angles are x - 10, x + 20 and 2x-30.

Sum of all angles of a triangle is 180.

x - 10 + x + 20 + 2x-30 = 180

4x - 20 = 180

x = 200/4 = 50

Angles are 50 - 10, 50 + 20, 100 - 30, i.e, 40, 70 and 70.
