Answer:
x=53
Explanation:
One way to solve this problem is by using the Pythagorean Theorem.
This states that the square of one "leg" of the triangle plus the square of the other "leg" of the triangle would equal the square of the hypotenuse, or the longest side of a triangle. Keep in mind that this only works for right triangles, where one angle is exactly 90 degrees.
This formula can be written as: a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse.
So, for this problem, let a=28, and b=45.
This gives us: 28^2 + 45^2 = x^2
And we can simplify this to: 2809 = x^2
Taking the square root of both sides gives us the answer, that x=53 units.
Hope this helps!
