ACT SAT Prep How to determine the SINE of an angle given a right triangle and it's sides

The video tutorial covers the basics of trigonometry, focusing on right triangles and the use of SOHCAHTOA to remember trigonometric ratios. It explains how to identify the sides of a triangle relative to a given angle and provides an example problem to demonstrate the application of these concepts.

What is the mnemonic used to remember the trigonometric ratios?

• SOHCAHTOA

• Pythagorean

• TRIGRATIO

• SINECOSINE

Which side of a right triangle is always the longest?

• Base

• Hypotenuse

• Opposite

• Adjacent

In trigonometry, what does the sine of an angle represent?

• Opposite over Hypotenuse

• Hypotenuse over Opposite

• Opposite over Adjacent

• Adjacent over Hypotenuse

How can the adjacent side of a triangle change?

• It changes based on the length of the hypotenuse.

• It changes depending on the type of triangle.

• It changes depending on the angle of reference.

• It changes based on the size of the triangle.

What is the sine of an angle if the opposite side is 12 inches and the hypotenuse is 13 inches?

• 13/12

• 5/12

• 12/13

• 1/2
