Answer:
2.meters
Step-by-step explanation:
Lenght of ladder = 4 m
θ = 30°
To obtain h;
Using Pythagoras rule :
Sinθ = opposite / hypotenus
Hypotenus = 4 ; opposite = h
Sin 30 = h / 4
0.5 = h / 4
h = 0.5 * 4
h = 2 m
Hence, distance between th efoot of ladder and the base of the wall is 2 m
Using the monthly payment formula, it is found that the amount he will have to pay each month is of $649.45.
<h3>What is the monthly payment formula?</h3>It is given by:
In which:
In this problem, considering that the down payment does not count for interest, the parameters are given as follows:
P = 130000, r = 0.0438, n = 30 x 12 = 360.
Then:
r/12 = 0.0438/12 = 0.00365 -> 1+r = 1.00365.
Then the monthly payment is given by:
A = 649.45.
