In triangle ABC, m?BAC = 50°. If m?ACB = 30°, then the triangle is triangle. If m?ABC = 40°, then the triangle is triangle. If triangle ABC is isosceles, and AB = 6 and BC = 4, then AC =

Respuesta :

use the pythagorean theorem: a^2 + b^2 = c^2

6^2 = 36

4^2 = 16

36-16 = 20.

the square root of 20 is either a.) the square root of 20 or b.) 4.4721... (rounded 4.5)
