The proportion given to us is
5.7/20 = x/200
Cross multiply:
5.7*200 = 20*x
1140 = 20x
Divide both sides by 20:
1140/20 = 20x/20
57 = x
Hello!
You can use the Pythagorean Theorem

c is the hypotenuse which is the side across the right angle

Subtract 25 from both sides

Take the square root of both sides
a = 10.9
The answer is D) 10.9 centimeters
