The cross section of a hopper for containing balls is shown.

what is the length of the top of the hopper?

enter your answer in the box.

round only your final answer to the nearest foot.

14 ft  

Step-by-step explanation:

If we label the vertices ABC as in the diagram below, we can use the law of cosines to calculate the third side AB of the triangle.

Data:

a = 13

b = 15

C = 59.5°

Calculation:  

c² = a² + b² -2abcosC

   = 13² + 15² - 2 × 13 × 15cos59.5

   = 169 + 225 - 390 × 0.5075

   = 394 - 197.9

   = 196.1

c = √ 196.1

   = 14 ft

answer: slight chance that it will happen

step-by-step explanation:

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
