For this problem you only need to look at two numbers out of the three that are given the number of basketball games is irrelevant . So why you want to do is divid the number of made shots by the number of attempted shots 69/93 and when the division is done you get .7419 then you shift the decimal point over two to the right and get 74.19% and round to the nearest tenth makes it so you get 74.2 %
This is a really vague question, but all i can assume from that is that all the sides of some triangle are congruent to their respective sides on the other triangle.
