Find the value of x in the triangle shown below 16 12 please put a valid explanation for the answer

x=10

Step-by-step explanation:

Pythagorean Thereom: a^2+b^2 = c^2 when the triangle is right which it is since the 90 degree angle is marked.

a=8 and b=6

8^2+6^2= 64+36 = 100

Take the square root of 100 and get 10.

step-by-step explanation:

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
