Question

Select the correct answer from each drop-down menu.

Triangle DEF is shown with angle D measuring 30 degrees and angle F measuring 60 degrees. Side DE is labeled f. Side EF is labeled d. Side DF is labeled e.
The product of sin 30° and sin 60° is same as the product of
and
A cos 60 degrees B tan 30 degrees and for the second drop down menu A cos 30 degrees B tan 60 degrees

Answer 1

cos 60 degrees

cos 30 degrees

Explanation:

its the big TM (tacoman)

Answer 2

• cos(60°)
• cos(30°)

Explanation:

You want the factors of a product that will have the same value as ...

sin(30°) · sin(60°)

Sine and cosine

We know that sin(θ) = cos(90° -θ). This means ...

sin(30°) = cos(60°)

sin(60°) = cos(30°)

Using these values, we can say ...

The product of sin 30° and sin 60° is same as the product of cos(60°) and cos(30°) .
