## tennis13 2 years ago One leg of a right triange mesures 15 m and the hypotenuse is 17 m, what is the length of the other leg?

1. Tttaammmaannnaa

8

2. lstrasmann

$a^2 + b^2 = c^2$$15^2 + b^2 = 17^2$$225 + b^2 = 289$$b^2 = 64$$b=\sqrt{64}$$b=8$

3. Tttaammmaannnaa

you have to use the formula: x^2 + y^2 = r^2. 15^2 + y^2 = 17^2 225 + b^2 = 289 b^2 = 64 b = 64−−√ b = 8

$\sqrt{64}$

6. lstrasmann

same formula as above, just plug in 52 for c and 38 for b and solve for a.
