In triangle ABC, angle C is straight, angle A is 2 times greater than angle B, what are angles A and B equal to?

triangle ABC, ∡ с – straight line.

1) Let x be the angle B. then the angle C = 2 * x, since the angle A is 2 times greater than the angle B.

2) The sum of two acute angles of a right-angled triangle is 90 °.

3) Let’s make an equation.

x + 2 * x = 90;

Here are some similar ones.

3 * x = 90;

x = 90/3;

x = 30;

4) 2 * x = 2 * 30 = 60;

∡ A = 30 ° and ∡ B = 60 °.
