Question

The measures of the angles of a triangle are shown in the figure below solve for (8x-15)9033

Answer 1

1) Bearing in mind that the sum of the interior angles of any triangle yields 180º.

2) Then we can write the following:

8x -15 + 90 +33 = 180º

8x +108=180º Subtract 108 from both sides

8x = 72 Divide both sides by 8

x = 9
