Question

Find the missing side of the triangle leave answer in simplist radical form

Answer 1

Answer: x = 3 √21

Step-by-step explanation:

you gotta use our good, old, trusty friend pythagorean theorem.

a^2 + b^2 = c^2

x^2 + 6^2 = 15^2

x^2 = 15^2 - 6^2

x^2 = 189

x = √189

x = √27 · 7

x = 3 √3 · 7

x = 3 √21
