Answer 2

Given - the measure of angle A is thrice the measure of Angle B

Find - the measures of angle A and Angle B

Solution - The measures of angle A and Angle B is 45° and 135° respectively.

Let the angle B be x. So, angle A will be 3x.

Now, as per the fact, the sum of these two angles will be 180°.

Expression it in the mathematical equation -

x + 3x = 180°

4x = 180°

x = 45°

So, the measure of angle B = 45°

The measure of angle A = 3x

The measure of angle A = 3*45

The measure of angle A = 135°

Thus, the measures of angle A and Angle B is 45° and 135° respectively.
