Answer:
B) 12
Explanation:
Hope the measure are the sides of right triangle.
Here c is the hypotenuse.
According to the Pythagorean theorem.
a^2 + b^2 = c^2
Now plug in a =16 and c = 20, we get
16^2 + b^2 = 20^2
256 + b^2 = 400
b^2 = 400 - 256
b^2 = 144
Taking square root on both sides, we get
b = √144
b = 12
Hope this will helpful.
