Grade 10 Algerbra help?

a^2 + b^2 = 169

a + b = 17

Solve for a and b.

(The original question was:

The hypotenuse of a right triangle has a length of 13 cm. The sum of the lengths of the two other sides is 17 cm. Find the unknown side lengths.)

Thanks

Perhaps try substitution —

a = 17 – b

Now put that into the first equation —

(17 – b)^2 + b^2 = 169

Then, simplify and solve for b, then insert that into the a + b = 17 equation to find a.

13 is part of the pythagorean triple 5, 12, 13 (a pythagorean triple is three numbers that can be the sides of a right triangle). I know this because my calculus teacher had us memorize a bunch of them (they come in handy when doing related rates problems.)
