Question

Solve for x. Determine the angles in the triangle.2X + 12X930

Answer 1

Given that the sum of the three interior angles of a triangle is equal to 180°, we can formulate the following equation:

2x + 1 + 2x + 93 = 180

4x + 94 = 180 (Adding like terms)

4x = 180 - 94 (Subtracting 94 from both sides of the equation)

4x = 86

x= 86/4 (Dividing by 4 on both sides of the equation)

x= 21.5

Replacing in the angles we have:

Angle 2x + 1 ---> 2(21.5) + 1= 44

Angle 2x ---> 2(21.5) = 43

The angles of the triangle are 43, 44 and 93.
