Question

Two sides of a right triangle are 8 and 12. Find the missing side of 8 and 12 are a leg and a hypotenuse.​

Answer 1

8.94 if no rounding is necessary.

Explanation:

Pythagorean Theorem. What we know is only one leg and the hypotenuse, sooo...

8² + b² = 12²

64 + b² = 144

Subtract 64 from both sides...

64 - 64 + b² = 144 - 64

b² = 80

`√(80)` = 8.94 if you're not rounding.
