The boat is 130 m from the base of a cliff. The cliff is 80m high. Determine, to the nearest degree, the angle of depression of the boat from the top of the cliff.

32 degrees (rounded to nearest angle)

Step-by-step explanation:

Using trigonometric ratios:

Please refer to the picture of my explanation below.

tan^-1 means inverse, so on calculator remember to use the inverse function, by shifting.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
