If you know the pythagorean ! in a right triangle the length of a hypotenuse is c and the length of one leg is a find the length of the other leg, if: 1.) c=5, a=3 2.) c=13, a=5; 3.) c=6, a=5.

Need on this geometry question. explain how you did it.

1c) the number 131 is a term in the sequence defined by the explicit rule f(n)=5n-4. which term in the sequence is 131? 2a) write the first four terms of the function f(n)=n^2-1 2b) what is the 10th term of the sequence defined by the explicit rule f(n)=n^2-1 2c) the number 224 is a term in the sequence defined by the explicit rule f(n)=n^2-1. which term in the sequence is 224?

The measure of an angle is 117°. what is the measure of a supplementary angle?
