Question

Find the length of the third side. If necessary, round to the nearest tenth. 6 8 there also a right angle

Answer 1

See below ↓

Explanation:

Given side lengths :

• 6
• 8

This question can be solved in two ways :

1. Taking the third side to be the hypotenuse (What you're probably looking for)
2. Taking 8 to be the hypotenuse (Probably not needed, but good for understanding the various possiblities)

Case 1

• By Pythagorean Theorem, as right angle is mentioned :
• 6² + 8² = x²
• x² = 100
• x = 10 [Your answer!]

Case 2

• 6² + x² = 8²
• x² = 64 - 36
• x² = 28
• x = 2√7 [Just in case!]

Hope it helps~
