Question

Find the missing side.​

Answer 1

The missing side is 5

Explanation:

Step 1: Use Pythagorean Theorem to find the hypotenuse

Since we are given two sides, a and b, we need to find the hypotenuse or c.

Formula:
`a^2 + b^2 = c^2`

Plug in

`(3)^2 + (4)^2 = c^2`

`9 + 16 = c^2`

`25 = c^2`

Square root both sides

`√(25) = √(c^2)`

`√(5^2) = c`

`5 = c`

Answer: The missing side is 5

Answer 2

5

Explanation:

This is a right triangle, but note that you only know the measurement of one angle, which is 90 degrees.

Use the following formula to solve:

a² + b² = c²

In which:

a & b = shorter sides

c = hypotenuse

Plug in the corresponding numbers to the corresponding variables:

(3)² + (4)² = ?²

Solve. Remember to follow PEMDAS. First, solve the exponents, then add:

(3)² = (3 * 3) = (9)

(4)² = (4 * 4) = (16)

9 + 16 = ?²

25 = ?²

Isolate "?". Root both sides:

√(25) = √(?²)

? = √25 = √(5 * 5) = 5

Your missing side's measurement is 5.
