anonymous · Answer

Using Pythagorean THeorem, can you figure out the hypotenuse AC?

anonymous · Answer

12.20?

anonymous · Answer

$$c^{2} = 5^{2} + 12^{2}$$$$c^{2} = 25 + 144$$$$c^{2} = 169$$$$c = 13$$

anonymous · Answer

oh sorry i did my math wrong . but 13 is what i meant

anonymous · Answer

Then, use the 30-60-90 triangle ratio.|dw:1341447822241:dw|
2x = 13
Solve for x because the distance you're looking for is what x is.

anonymous · Answer

is it 6.5?

anonymous · Answer

Yup :)

anonymous · Answer

thankyou . Nobody in my family really knows how to do math so im kind of stuck with trying to learn it myself.
