anonymous 3 years ago A 30°-60°-90° triangle has a hypotenuse with a length of 10. What is the length of the longer leg of the triangle?

Longer leg is opposite to 60 degree angle. And, side opposite to 60 degree angle is $\sqrt3/2$ times the hypotenuse.

idk

can u explain ur drawing?

see, if the hypotenuse is 1, the triangle looks like this : |dw:1357661727471:dw| now if the hypotenuse is 10, just multiply all sides by 10...as simple as that.

ooooh i seee

in general, if the hypotenuse =h, then|dw:1357661837153:dw| here h=10 you understood now ?
