Question

Write the equation you would use to find x, then solve for x.

Answer 1

Answer:

x + 6x+10   + x+2 = 180

x = 21

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

x + 6x+10   + x+2 = 180

Combine like terms

8x + 12 = 180

Subtract 12 from each side

8x+12-12 = 180-12

8x =168

Divide each side by 8

8x/8 = 168/8

x =21

Answer 2

Answer:

Step-by-step explanation:

by angle sum property of a triangle ,

x+x+2+6x+10=180

8x =180-12

8x =168

x =168/8

x=21

hope it helpss
