The lengths of the sides of a triangle are 10, 17 and 21. How long is the altitude of the triangle to longest side?

Use the pythagoreanThearom to find the altitude of the triangle then write the ratio. Altitude: 21. 

Remember Pythagorean Thearom is a^2+b^2=c^2 so you do x^2+21^2=17^2. And x is the altitude.
