Three angles of a triangle are in the ratio 1:1:2, the angles will be _____?

45°, 45°, 90°

30°, 30°, 120°

50°, 50°, 80°

None of these

Let's denote the three angles as x, x, and 2x, since they are in the ratio 1:1:2.

The sum of the angles in a triangle is always 180°:

x + x + 2x = 180°

Combine like terms:

4x = 180°

Divide by 4:

x = 45°

Now that we know x, we can find the other angles:

x = 45°

2x = 90°
