Best ResponseYou've already chosen the best response.0ok. But we do not have a leg length so what do we do?

Best ResponseYou've already chosen the best response.0This is the other special right triangle. Everything is related to the short leg which is the leg opposite the 30 degree angle.

Best ResponseYou've already chosen the best response.0short leg times 2 = hypotenuse short leg times sqrt3 = long leg

Best ResponseYou've already chosen the best response.0A ladder leans against a house at a 60° angle to the ground. If the ladder extends to a length of 132 inches, what is the height of the house to the nearest hundredth of an inch? House with a ladder measuring 132 inches forming a right triangle. The base angle formed by the ladder is 60 degrees.

Best ResponseYou've already chosen the best response.0It is the same triangle but this time we know the hypotenuse and have to find the long leg.

Best ResponseYou've already chosen the best response.0First, find the short leg. What is it?

Mertsj

Best ResponseYou've already chosen the best response.0Well then pick up you calculator and multiply sqrt3 by 66 and round to the nearest hundredth

Best ResponseYou've already chosen the best response.0wait! i have one last question!!!! how do you find the short leg if the give you the long leg?

Mertsj

Best ResponseYou've already chosen the best response.0Well, if you multiply the short leg by sqrt3 to get the long leg, then you should divide the long leg by sqrt3 to get the short leg.
