Question

Find the missing length 10, 3, C

Answer 1

119

Explanation:

• The Pythagorean Theorem says that the sum of the squares of a right triangle's shorter sides equals the square of the longest side (i.e., the hypotenuse, which is always opposite the right angle).

Thus, we can find c by plugging in 10 for a and 3 for b in the Pythagorean Theorem:

Step 1: Plug in 10 for a and 3 for b. Then simplify.

10^2 + 3^2 = c^2

100 + 9 = c^2

119 = c^2

Step 2: Take the square root of both sides to solve for c, the missing length:

√(119) = √(c^2)

√119 = c

Thus, c = √119.

Since your website only wants you to write the number without the square root brackets, type 119.
