A28ft boat ramp makes a 10 degree angle with water. what is the height of the ramp above the water at the highest point?

the height of the ramp above the water at the highest point is 2.0832ft

Step-by-step explanation:

The ramp makes an angle of 10 degrees with water and forms a right angle triangle.

The height of the ramp above the water at the highest point represents the opposite side of the right angle triangle.

The length of the ramp represents the hypotenuse of the right angle triangle. Therefore, to determine the height of the ramp above the water at the highest point, h , we would apply the Sine trigonometric ratio.

Sin θ = opposite side/hypotenuse. Therefore,

Sin 10 = h/12

h = 12Sin10 = 12 × 0.1736

h = 2.0832

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
