Give another name for DE.

• e

• d

• f

• Depression

In △ABC label the sides: opposite, adjacent and hypotenuse.

• Opposite: AB, Adjacent: BC, Hypotenuse: AC

• Opposite: BC, Adjacent: AB, Hypotenuse: AC

• Opposite: AC, Adjacent: BC, Hypotenuse: AB

• Opposite: AB, Adjacent: AC, Hypotenuse: BC

For △ABC in Question 2, if you were given the length of the Opposite and Hypotenuse sides, what trigonometric ratio would you use to solve for angle θ?

• Sine (sin)

• Cosine (cos)

• Tangent (tan)

• Secant (sec)

Using your calculator, solve for the unknown pronumeral in the following statement: v = 17 cm × cos 62°14'

• 7.91 cm

• 7.92 cm

• 7.98 cm

• 7.99 cm

The sine ratio is defined as:

• hypotenuse/opposite

• adjacent/opposite

• hypotenuse/adjacent

• opposite/hypotenuse

The cosine ratio is defined as:

• hypotenuse/opposite

• adjacent/opposite

• hypotenuse/adjacent

• adjacent/hypotenuse

The tangent ratio is defined as:

• hypotenuse/opposite

• adjacent/opposite

• hypotenuse/adjacent

• opposite/adjacent

Which trigonometric ratio should be used to find the value of the pronumeral in the following diagram?

• tan

• sin

• cos

• none of the above

Find the value of the pronumeral.

• 17

• 24

• 11

• 13

Solve for the pronumeral in the given diagram.

• w = 10

• w = 5

• w = 7

• w = 10
