Zhang is constructing a 4-ft loading ramp. The length of the back of the base must by 12.8-ft. How long must the entire base be? Choose 1 equation, choose 1 answer for the front of the base and choose 1 answer for the total base. Equation: \frac{4}{12.8}=\frac{x}{4}
12.8

\rightarrow→ 4x=51.24x=51.2

Front of Base: 0.078 ft

Front of Base: 1.25 ft

Total Base: 14.05 ft

Total Base: 12.878 ft

step-by-step explanation:

i’m kinda new to precal but your answer should be 21. hope i got it right.

step-by-step explanation:

using the formula for pythagorean theorem (a2+b2=c2)(the twos are exponents), and knowing that you have b squared and c squared, just reverse it. 26 squared minus 10 squared equals c squared. 26 squared is 676 and 10 squared is 100. you get 576, then use your square roots to undo the squared numbers to get 24.
