Find the unknown side of the triangle
bottomi is 36 m
and right side is 15m

A^2+b^2=c^2
36^2+15^2=c^2
1296+225=1521
square root of 1521 is 39.
c=39

so the unknown side of the triangle is 39m.

50 points decreased by 26% is 37, because to find the percentage, all you have to do is multiply the number you are trying to decrease the percentage of, and take the percentage as a decimal form and multiply the two. then, you have to subtract that number from the base to get your final answer. : )
