Question

Find the value of x in the triangle shown below

Answer 1

sqrt(104) =x

Explanation:

We can use the Pythagorean theorem since this is the right triangle.

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.

2^2 + 10^2 = x^2

4+100 = x^2

104 = x^2

Take the square root of each side

sqrt(104) = sqrt(x^2)

sqrt(104) =x
