Answer: x = 17
Step-by-step explanation:
2+x = 2x-15
subtract x on both sides
2 = x -15
add 15 to both sides
17 = x
------------------
17+2 = 2(17)-15
19 = 34 -15
19 = 19
Since ABC is a right triangle, we can use Pythagorean Theorem to solve for side AB.
Pythagorean Theorem: a^2 + b^2 = c^2
4^2 + 7^2 = c^2
16 + 49 = c^2
65 = c^2
c = 8.06
Hope this helps!! :)
