Problem#1
Find the length x in each triangle. Express your answer in simplified radical form.

Leg 1 = 8
hypotenuse = 10
leg 2 = x

My answer is: x = ã27

Problem #2
Geometry. For the home described in exercise 15, if the roof is 7 m from peak to eave and the attic space is 3 m high at the peak, how long does each of the pieces of insulation need to be? Round to the nearest tenth.

My anwer: b = 6.3m


for the first one I got an answer of 6
I don't understand your symbol ã

Your second answer is right


sorry the symbol a was suppost to come out as a radical sign. how did you get 6

x^2+8^2=10^2
x^2+64=100
x^2=36
x=6
