Question

What are the angle measures of the triangle?

Answer 1

Answer: 30, 60, 90 triangle ==> Option 3

Step-by-step explanation:

Lets say Angle A is the angle opposing the line of a triangle that has the length of 6. Lets say Angle B is the angle opposing the line of the same triangle that has the length of $6\sqrt{3}$.

sin A=6/12=1/2

sin A=30 degrees.

sin B=$\frac{6\sqrt{3}}{12}$=$\frac{\sqrt{3}}{2}$

sin B=60 degrees.

Hence, triangle is 30, 60, 90 triangle ==> Option 3
