Answer:

Step-by-step explanation:
AD = 4
AC = 11
DC = 11 - 4 = 7
First, find BD using the right triangle altitude theorem:

Plug in the values


Use pythagorean theorem to find x:
x² = AD² + BD²
Plug in the values





Take the square root of both sides




I believe the answer is 4x + 8. you multiply 4 by x which makes 4x. Than you multiply 4 by 2, making 8.
Answer:
