Answer:

Step-by-step explanation:

A right angle triangle is formed. The distance from the top of the tree to your position represents the hypotenuse of the right angle triangle. The height of the tree represents the opposite side of the right angle triangle.

The height of the tree from the ground is the sum of the length of the opposite side and your height.

To determine the length of the opposite side, h, we would apply the Sine trigonometric ratio.

Sinθ = opposite side/hypotenuse Therefore,

Sin 66 = h/108

h = 108Sin66 = 108 × 0.9135

h = 98.66

Therefore, height of tree is

98.66 + 5.75 = 104.41 feet

Rewrite the fraction in the sentence below as a percentage.

Answer:

86%

Step-by-step explanation:

A percentage is a number or a ratio expressed as a fraction over 100. For example, 50% in fraction form is known as 50/100. 45% is known as 45/100.

Lets say the fraction was 43/50. We already know that a percentage is a number expressed as a fraction over 100, in order to convert this fraction into a percentage, we would have to multiply the denominator by a certain number in order to make it 100.

43/50 = x/100

If we multiply 50 × 2 = 100, so now we have to do the same for the numerator, and also multiply it by 2.

43 × 2 = 86

50 × 2 = 100

Now we know that the fraction is 86/100, now in order to convert it into percantage form, it would just be 86%
