Learn how to determine the sine cosine and tagent given a right triangle

The video tutorial explains the significance of angles in triangles, focusing on the properties of 30-60-90 triangles. It covers the sine, cosine, and tangent functions, emphasizing the relationships between angles and sides. The tutorial also highlights the importance of understanding adjacent sides and simplifying radical expressions.

In a 30-60-90 triangle, which side is always opposite the 30-degree angle?

• Hypotenuse

• None of the above

• Opposite

• Adjacent

What is the sine of a 30-degree angle in a 30-60-90 triangle?

• 1/2

• sqrt(3)/2

• sqrt(3)/3

• 1

How does the adjacent side change when considering a 60-degree angle in a 30-60-90 triangle?

• It becomes the opposite side

• It remains the same

• It becomes the hypotenuse

• It changes based on the angle

What is the cosine of a 30-degree angle in a 30-60-90 triangle?

• 1

• sqrt(3)/2
