Question

Find the value of x in the triangle shown below

X=2
X=5
X= √5
X= √17

Answer 1

the answer is
`√(17)`

Explanation:

the Pythagorean theorem is
`a^(2)` +
`b^(2) = c^(2)`. c is always the hypotenuse (the longest side) and a and b are the legs (the shorter sides) so 1 squared plus 4 squared is 17. there is no whole square root of 17 so the answer is
`√(17)`
