Use the Pythagorean theorem (a^2 + b^2 = c^2)
7^2 + 24^2 = x^2
x^2 = 625
x = 25
Answer:
<h2>x = 1</h2>
Step-by-step explanation:
If you would like to solve the following proportion 15 / 21 = 5 / x, you can do this as follows:
15 / 21 = 5 / x /*x
15 / 21 * x = 5 /*21
15 * x = 5 * 21 /15
x = 5 * 21 / 15
x = 7
The correct result would be C. 7.
