Question

The interior angles of a triangle have measures (2x - 5), (4– 1), and 30°

What is the value of x?
Enter your answer in the box.
​

Answer 1

Answer: x=26

Explanation:

1. Write the equation 2x-5+4x-1+30=180 because all triangle angles add up to 180°

2. Simplify the equation by combining like terms. Write the equation as 6x+24=180

3. Subtract 24 from both sides. Write the equation as 6x=156.

4. Divide 156/6 and get 26. That is your answer (x=26).
