Double Triangle Trigonometry Quiz

What is the primary trigonometric function used to relate the sides of the small triangle to the angle?

• Sine

• Cosine

• Tangent

• Secant

In the small triangle, if the angle is 48 degrees and the opposite side is 200, what is the formula to find the adjacent side b?

• b = tan(48) / 200

• b = 200 + tan(48)

• b = 200 * tan(48)

• b = 200 / tan(48)

When solving for side a in the big triangle, what is the shortcut mentioned for when the variable is in the denominator?

• Subtract the variable from both sides

• Flip the variable with the numerator from the other side

• Multiply both sides by the variable

• Add the variable to both sides
