x = sqrt(45)
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle
a^2 + b^2 = c^2
where a and b are the legs and c is the hypotenuse
2^2 + x^2 = 7^2
4+x^2 = 49
Subtract 4 from each side
4-4+x^2 = 49-x
x^2 = 45
Take the square root of each side
sqrt(x^2) = sqrt(45)
x = sqrt(45)
