Question

Look at the triangle below which of the following represents two of the angle measures of the triangle

Answer 1

x = 7

two of the angles 60 and 80

Explanation:

The sum of interior angles in a triangle is equal to 180

8x + 4 + 6x - 2 + 10x + 10 = 180 add like terms

24x + 12 = 180 subtract 12 from both sides

24x = 168 divide both sides by 24

x = 7 replace x with 7 in the equation to find the angle measures

6x - 2 = 40

10x + 10 = 80

8x + 4 = 60
