Answer 2

All the angles in a triangle add up to 180.

You know it's a right triangle, so one angle is 90.

So 90, 6x-10, and 2x-4 all add up to 180. Now set up the equation and then solve for x.

Answer 3

(6x-10) + (2x-4) =90 because the two remaining angles must add up to 90

6x + 2x -10 -4 = 90
8x -14 =90

8x =90 +14 =104
x= 104/8 = 13
