Aplane flying at a certain altitude is observed from two points that are 3 miles apart. the angles of elevation made by two points are 55 and 72, as seen in the diagram. the altitude of the plane to the nearest tenth of a mile is ?

The altitude of the plane is 8 miles

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC

tan(72°)=h/x

h=xtan(72°) -----> equation A

In the right triangle ABD

tan(55°)=h/(x+3)

h=(x+3)tan(55°) -----> equation B

equate equation A and equation B and solve for x

xtan(72°)=(x+3)tan(55°)

xtan(72°)-xtan(55°)=3tan(55°)

x[tan(72°)-tan(55°)]=3tan(55°)

x=3tan(55°)/[tan(72°)-tan(55°)]

Find the value of h

h=xtan(72°)

h=[3tan(55°)*tan(72°)]/[tan(72°)-tan(55°)]

h=8 miles

see attached

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

steve should create a type of business report called a business plan. the correct option among the options that are already given in the question is the last or the fourth option. this business report created by steve will actually influence the investors about investing their money in steve's business. this business report will have all the details about the business, the amount of investment required and the amount of expected profit.
