Step-by-step explanation:

Given :

1- cosA = 1/2

or, CosA = 1 -1/2

Therefore ; CosA = 1/2 = b/h

According to the Pythagoras theorem,

P = root under h^2 - b^2

= root under (2)^2 - (1)^2

= root under 4 -1

= root 3

Again,

SinA = P/h

= root 3 / 2

The principal amount for room loan = $ 3,800

The rate of interest applied = 11% compounded annually

The time period of loan = 3 years

Amount = Principal × (1+\dfrac{\textrm rate}{100})^{\textrm time}

or, A = $ 3,800 × (1+\dfrac{\textrm 11}{100})^{\textrm 3}

or, A = $ 3,800 × (1.11)³

or,  A = $ 3,800 × 1.3676

∴ A = $ 5,196.88

So, Amount after 3 years = A = $ 5,196.88
