Mastering Right Triangle Trigonometry with SOHCAHTOA

The video tutorial introduces trigonometry concepts for the SAT, focusing on the mnemonic SOA for right triangle trigonometry. It explains how to use sine, cosine, and tangent functions with right triangles, providing detailed examples and a practice question to reinforce learning. The tutorial emphasizes the importance of practice to improve SAT scores.

What does the mnemonic SOHCAHTOA help you remember?

• Steps to solve algebraic equations

• Methods to calculate angles in any triangle

• Relationships between sides and angles in right triangles

• Formulas for calculating area of circles

In the context of a right triangle, what does the 'S' in SOHCAHTOA stand for?

• Scalar

• Segment

• Sine

• Solution

If the side opposite the angle is 5 and the hypotenuse is 13, what is the sine of the angle?

• 12/13

• 13/5

• 5/13

• 5/12

What does the 'C' in SOHCAHTOA represent in trigonometric functions?

• Cotangent

• Cosecant

• Cosine

• Cubed root

For a right triangle with an adjacent side of 12 and hypotenuse of 13, what is the cosine of the angle?

• 12/13

• 13/12

• 5/13

• 12/5

What does the 'T' in SOHCAHTOA stand for?

• Terminus

• Triangle

• Tangent

• Total

If the opposite side is 5 and the adjacent side is 12, what is the tangent of the angle?

• 5/12

• 13/5

• 12/5

• 5/13

How would the tangent change if the opposite and adjacent sides are switched?

• 12/5

• 13/12

• 12/13

• 5/12

Using the cosine function, how do you calculate the hypotenuse if the adjacent side is 6 and the cosine of the angle is 0.74314?

• 6 + 0.74314

• 0.74314 / 6

• 6 / 0.74314

• 6 * 0.74314
