Question

What is the length of the missing leg in the triangle below? 15 yd 가 12 yd

Answer 1

We have a right triangle, we can use the Phytagorean Theorem in order to find the missing side

`c^2=a^2+b^2`

we have

c=15

a=12

b?

we clear b of the formula above

`b=\sqrt[]{c^2-a^2\text{ }}`

then we substitute the values

`\begin{gathered} b=\sqrt[]{15^2-12^2} \\ b=9 \end{gathered}`

the answer is

b=9 yards
