In the KLM triangle, the angle is 24 degrees and the angle B is 2 times the angle A

In the KLM triangle, the angle is 24 degrees and the angle B is 2 times the angle A Find the degree measure of the angle N and Determine the type of triangle.

Given:
triangle АNВ,
angle B = 2 * angle A,

angle АNВ = 24 degrees.
Find the degree measures of angles: angle A, angle B -?
Solution:
Consider the triangle AMN.
Let the degree measure of angle A is equal to x degrees, then the degree measure of angle B is equal to 2 * x degrees. We know that the sum of the degree measures of a triangle is 180 °. Let’s make the equation:
x + 2 * x + 24 = 180;
x + 2 * x = 180 – 24;

x + 2 * x = 156;

3 * x = 156;
x = 156: 3;
x = 52 ° – the degree measure of the angle A;
52 * 2 = 104 ° – degree measure of angle B.
Answer: 104 °; 52 °.
