yep

Answer 3

and were is the triangle

Answer 4

It doesn't show it. The answers are:

A. 30°, 60°, 90°

B. 45°, 45°, 90°

C. 60°, 60°, 60°

D. 30°, 52°, 60°

Answer 5

This triangle is a half of a quadrilateral triangle, therefore, the angles measures are: 30, 60, 90.

Answer 6

Thank you! Can you tell me how you figured it out?

Answer 11

There are many ways.
a) use the right triangle identity: sise^2 + side^2 = hypotenuse^2
(3)^2 + (3V3)^2 = (6)^2
9 + 27 = 36
b) use triangle trigonomrtry -> sin A = 3/6 = 1/2 = sin 30 deg --> A = 30 deg
sin B = 3V3/6 = V3/2 = sin 60 deg. --> B = 60 deg
