Using special right triangles and trig to find the value of sind 30 degrees

The video tutorial explains the properties of special right triangles, specifically the 30-60-90 triangle. It covers how to assign values to the sides of the triangle and verify their ratios. The tutorial also demonstrates how to calculate the sine of 30 degrees using these properties, emphasizing the relationship between the sides of the triangle and trigonometric functions.

In a 30-60-90 triangle, if the shortest side is X, what is the length of the hypotenuse?

• X * sqrt(3)

• X

• 2X

• X/2

What is the length of the longer leg in a 30-60-90 triangle if the shortest side is X?

• X

• X * sqrt(3)

• 2X

• X/2

If a triangle has sides in the ratio 1:2:sqrt(3), what type of triangle is it?

• 45-45-90

• Isosceles

• Equilateral

• 30-60-90

What is the sine of 30 degrees?

• 0

• sqrt(3)/2

• 0.5

• 1

How can you verify the sine of 30 degrees using a calculator?

• By checking if it equals 1

• By checking if it equals 0

• By checking if it equals 0.5

• By checking if it equals sqrt(3)/2
