5,998.7714 ft
Step-by-step explanation:
Well find x in the illustration;
First To find the opposite side of the right-angled triangle we'll using tangent of the given angle
Tangent Ф = Length of the opposite side / Length of the adjacent side
Tan 43 = h / 6390
h = Tan (43) * 6390
h = 5,958.7714 ft
Then we'll add the height of the beacon which is 40 ft above ground;
x = 5,958.7714 ft + 40 ft
x = 5,998.7714 ft

Given parameters:
Principal = £1300
Interest rate = 5%
Duration = 2yrs
Unknown:
Total amount of Dan's principal = ?
To solve this problem, we apply the equation below:
Total investment worth = Principal + interest
Interest =
where P is the principal
R is the rate
T is the time
Now, input the parameters;
Total investment worth = £1300 + £
= £1300 + £130
= £1430
The amount after two years is £1430
