## anonymous one year ago I'll fan and give medal! Match the length of a right triangle's legs with the exact length of its hypotenuse. http://assets.openstudy.com/updates/attachments/53ea874ee4b0f30a87d194a4-mlgpro-1407879011833-screenshot20140812at5.08.08pm.png

$a^2+b^2=c^2\\ \sqrt{a^2+b^2}=c$ so for the first one $\sqrt{9^2+11^2}=\sqrt{81+121}=\sqrt{202}$ others are similar

@satellite73 what would the equation be for seven and the square root of 140

3. anonymous

the same idea $\sqrt{7^2+\sqrt{140}^2}=\sqrt{49+140}=\sqrt{189}$

@satellite73 so I don't actually square the numbers are square roots?

@satellite73 so #3 equals B and #4 equals D right?
