Answer:
Explanation:
In 30, 60, and 90 triangles, it includes sides with ratios 1, 2x, and xsqrt3 with 2x reflective of 90, xsqrt3 of 60, and 1 of 30.
So if 2x = 6, then x = 3 so 3sqrt3 = 5.19. Using the Pythagorean theorem we find that the last length is 3.
If xsqrt3 = 3, then x = sqrt3, angle reflective of 90 is 2sqrt3.
