Help a gang out here!!!

Answer 1

..he sum of the angles of a triangle = 180°

5x-14+4x+16+4x-17=180

13x-15 =180

13x = 180+15

x=15°

Explanation:

Answer 2

x = 15

Explanation:

the sum of the 3 angles in a triangle is 180°

sum the 3 angles and equate to 180

5x - 14 + 4x + 16 + 4x - 17 = 180 , simplify left side

13x - 15 = 180 ( add 15 to both sides )

13x = 195 ( divide both sides by 13 )

x = 15
