Question

Hey can anyone pls help me in dis real quick!!!!

Answer 1

The Unknown side of the triangle is 13.19

Explanation:

To find it you would draw a rectangular prism and you would draw a triangle in the rectangular prism then you would draw another triangle with the length of 7cm and he width x and so your equation would be
`y^(2) = 7^(2) +x^(2)` so first you would find x and so since the rectangular prism width is 10 and the length is 5 you would do
`x^(2) =5^(2) +10^(2)` so then your equation would be
`y^(2) =7^(2) +5^(2) +10^(2)` do the math that would give you
`y^(2) = 174` then you would do
`y = √(174) = 13.19` and so your answer is 13.19

I hope I didn't write to much
