Question

Look at the triangle shown below.

107º
(2x - 5)º
xº
Which equation can be used to find the value of x?
O x + 2x - 5 = 107
O 107 + 2x - 5 = 180
107 + 2x - 5 + x = 180
X + 2x -5 = 180

Answer 1

C

Explanation:

Answer 2

C. 107 + 2x - 5 + x = 180

Explanation:

The sum of interior angles of a triangle = 180°

Therefore, to find x, we would state that all three angels indicated in the figure above equals 180°.

Thus:

107 + 2x - 5 + x = 180

We can solve and find the value of x using the equation above
