Part III: Complete a formal proof to validate your findings from Parts I and II. (9 points)

Step 1: Every proof needs Given and Prove statements. Use the endpoints on the diagram to write a Given statement indicating the down tube is longer than the top tube. Prove the relationship between the opposite angles of the given sides. (2 points; 1 point for the Given statement, 1 point for the Prove statement)

Given:

Prove:

He an put 20 of the additional boxes in the elevator. 10*37.5= 137.5
450-137.5=312.5      312.5/15.5=20.12903226- round down to 20.

Check: 20*15.5=310 & 10*37.5= 137.5 so 137.5+310=447.5- He cannot carry anything else because then it would go over.

So he can put 20 additional boxes+ the original 10 boxes.

(Also you may need to know John's weight- you did not include it. This would affect the number of additional boxes that can be put on.)

Hope this helps!
Can u plz mark me as brainliest?  I really need it!
