Question

A certain triangle has a 30 angle and a 60 angle.

Answer 1

Explanation:

It is B, The longest side is sqrt 3 times as long as the shortest side.

Attached is a image showing the side length rules for 30-60-90 triangles.

Hope this helps :)

Answer 2

The answer to this is A. The longest side of a
30-60-90 triangle is twice the length of the shortest side. That’s why the sine of 30 is 1/2, because it’s half the length of the hypotenuse
