The answer is D. To solve for the third side we use the Pythagorean Theorem. It is expressed as the squared of the hypotenuse is equal to the sum of the squares of the two remaining sides, c^2 = a^2 + b^2.

We are given the sides of the triangle which were 20 and 28 thus we can solve for the hypotenuse.

c^2 = 20^2 + 28^2
c = √(20^2 + 28^2)
c = 34.41

Answer:

34.41

Step-by-step explanation:

Using the Pythagorean Theorem:

a^2 + b^2 = c^2

20^2 + 28^2 = c^2

400 + 784 = c^2

1,184 = c^2

sqrt(1,184) = c

34.41 = c
