Question

In a triangle, the measure of the second angle is twice the measure of the first angle. The third angle is equal to the sum

of the other angles,
Which of the following could represent the measures of the three angles?
Ox, 2%, 4%
OX, 2x, 3x
OX, 2x, 2x

Answer 1

x, 2x, 3x

Explanation:

If we have angle x as one angle, and the 2nd angle is twice the angle, the 2nd angle will be 2x. If the 3rd angle is the sum of the 1st angle and the 2nd angle, we have 2x + x, which equals 3x.
