Step-by-step explanation:
<u>Right Triangles</u>
A right triangle can be identified by the fact it has an internal angle of 90°. In a right triangle, the trigonometric ratios stand.
Let's consider the triangle to the left. We need to calculate side c, one of the legs of the triangle. We can use the angle adjacent to it (60°) or the angle opposite to it (30°) with the appropriate trigonometric ratio.
We'll use the adjacent angle, and

Solving for c

Rationalizing

Now for the triangle to the right. The side h is the hypotenuse. Again, any of the two angles can be used (though they are equal, for it's an isosceles triangle). For any of them it is true that

The value of her investment at the end of 3 years is £10955.08
<h3>How to determine the value?</h3>
The given parameters are
- Principal, P = £5000
- Rate, r = 6%
- Time, t = 3 years
The value is then calculated as:
Value = P * P(1 + r)^t
So, we have:
Value = 5000 + 5000 * (1 + 6%)^3
Evaluate the expression
Value = 10955.08
Hence, the value of her investment at the end of 3 years is £10955.08
