Question

(2x + 15) Find the value of x? in the triangle

Answer 1

The given triangle is a right angle triangle. This means that one of the angles is 90 degrees. Recall, the sum of the angles in a triangle is 180 degrees. This means that

2x + 15 + x + 90 = 180

2x + x + 15 + 90 = 180

3x + 105 = 180

3x = 180 - 105

3x = 75

x = 75/3

x = 25
