The following formula is to find the surface area of an equilateral triangular prism, a = 3sh + sw use the formula and the diagram on the right to answer the following: questions: 1) solve the formula for's (side length of the base), show your work 2) if the surface area measures 75.4 inches square how much is the side length of the base? (round the decimal to 2 places) you can work on a papen take a picture of your work and upload your work in here,

Part 1)

Part 2)

Step-by-step explanation:

Part 1) Solve the formula to s

we have

Solve for s

That means -----> isolate the variable s

Factor the variable s in the right side

Divide by (3H+w) both sides

Rewrite

Part 2) If the surface area measures 75.4 inches square how much is the side length of the base?

we have

substitute

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
