What is the length of EF in the right triangle below?

Answer:
F 24
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem
a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse
10^2 + EF^2 = 26^2
100 + EF^2 = 676
Subtract 100 from each side
100-100 + EF^2 = 676-100
EF^2 = 576
Take the square root of each side
sqrt(EF^2) = sqrt(576)
EF = 24
Answer:
F 24
Step-by-step explanation:
You have to use the Pythagorean Theorem
a²+b²=c²
(a and b are the legs of the triangle and c is always the hypotenuse)
a²+10²=26²
a²+100=676; now isolate the a² by subtracting 100 from both sides.
a²=576; now square root each side (gets rid of the squared)
a=24
