In Triangle A B C, what is the value of x? Triangle A B C. Angle A is (10 x minus 10) degrees, angle B is (8 x) degrees, angle C is (10 x + 8) degrees. 5.5 6.5 55 65

x = 6.5

Step-by-step explanation:

The sum of the angles of a triangle is 180

8x+ 10x-10 + 10x +8 = 180

Combine like terms

28x -2 = 180

Add 2 to each side

28x-2+2 = 180+2

28x=182

Divide by 28

28x/28 = 182/28

x =6.5

x = 6.5

Step-by-step explanation:

In a triangle, the sum of the measures of the angles equals 180 deg.

8x + 10x - 10 + 10x + 8 = 180

28x -2 = 180

28x = 182

x = 6.5
