Question

Determine the missing side lenght of a right triangle when given a=14 and b=7

Answer 1

Answer:

√245 or 15.65247...

Step-by-step explanation:

a² + b² = c²

14² + 7² = c²

196 + 49 = c²

245 = c²

√245 ≈ c

Answer 2

When you have a right triangle, you can use the Pythagorean Theorem to find the missing side length. (but it only works for RIGHT triangles)

Pythagorean Theorem:

a² + b² = c²         Since you know a=14 and b=7, plug it into the equation

(14)² + (7)² = c²

196 + 49 = c²

245 = c²

√245 = c    or 15.6524758425 = c
