The cosine of an angle is defined as the sine of the complementary angle. The complementary angle equals the given angle subtracted from a right angle, 90°. For instance, if the angle is 30°, then its complement is 60°. Generally, for any angle θ, cos θ = sin (90° – θ).
Each of the eggs is 3.5 and a dozen is 12
So, we multiply 12 by 3.5 to get 42 grams
The dozens of eggs is 42 grams.
Hope this helps!
Answer:
≈ 33.2 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = (9, - 4) and (x₂, y₂ ) = (- 22, 8)
d = 
= 
= 
=
≈ 33.2 ( to 1 dec. place )
1 mile is equal to 1.6 kilometers, so 8 miles (using a direct proportion) should be equal to 8 * 1.6 = 12.8 kilometers. The cyclist rides at 12.8 kilometers per hour. In four hours, the cyclist would have rode 12.8 * 4 = 48 + 3.2 = 51.2 kilometers.
