SIZIF [17.4K]3 years ago
3 0

Answer:

By using the value of cosine function relations, we can easily find the value of sin 120 degrees. Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value. We know that the value of cos 30 degrees is √3/2. Therefore, sin 120° = √3/2

solmaris [256]

Answer:

the correct answer is 24 quarters

Step-by-step explanation:

Since Ben parks for 3 hours and one hours costs $2

Therefore 3 hours = $2.00 × 3 hours = $6.00

Next, note that 1 quarter = 25 cents (same as One-quarter of a dollar)

∴ 1 quarter = 1/4 dollar

= 1 quarter = 0.25 dollars.

$0.25 = 1 quarter

∴ $6 = (1/0.25) × 6 = (6 ÷ 0.25) = 24 quarters

Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only) (6 points)
wolverine [178]

Answer:

35.68°

Step-by-step explanation:

In the picture attached, the triangle is shown.

From sine definition:

sin(y) = opposite/hypotenuse

The leg measuring 7 units is opposite to angle y, and the hypotenuse measures 12 units, therefore:

sin(y) = 7/12

y = arcsin(7/12)

y = 35.68°
