The length of the wall is approximately 16.7ft high.

To solve this problem, we would use trigonometric ratios.

The sine angle between any two body is the ratio between the opposite and hypotenuse.

Data given;

  • angle = 68 degree
  • hypotenuse = 18 foot
  • opposite = ?
<h3>Trigonometric Ratio</h3>

sin x = \frac{opposite}{hypotenuse}\\sin 68 = \frac{opposite}{18}\\opposite = 18 sin68\\opposite = 16.68ft

From the above calculation, the length of the wall is approximately 16.7ft

Art [367]

Answer:

The money was left untouched for 2 years and 6 months or just 2.5 years

Step-by-step explanation:

In this question, we are asked to calculate the time taken for an amount deposited to earn a certain amount of interest.

Mathematically, simple interest can be calculated using the formula;

I = PRT/100

where I is the interest accrued which is 3696.88 - 3,500 = 196.88

P is the principal which is the amount deposited = 3,500 according to the question

R is the rate which is 2.25% according to the question

T is the time which we are to find

we can rearrange the formula making T the subject and we obtain the following;

T = 100I/PR

substituting the values listed above we have;

T = (100 * 196.88)/(3500 * 2.25)

T = 19688/7875

T = 2.5 years or 2 years 6 months
