Answer:
x = 13
Step-by-step explanation:
Split the triangle in to two. The dimensions of each will be 12 x 5 x X.
Use the pythagorean theorem.
h^2 = 144 + 25 = 169
h = sqrt 169 = 13
Answer:
Since we know that ABCD is an isosceles trapezoid, we can also asume that its diagonals have the same length, which means:
AC = BD
=> 7x - 21 = 5x + 13
=> 7x - 5x = 21 + 13
=> 2x = 34
=> x = 34/2 = 17
So the answer is C.
