In δuvw, the measure of ∠w=90°, the measure of ∠v=72°, and vw = 6.1 feet. find the length of uv to the nearest foot.

The length of UV is 19.7 ft.

Solution:

The given is a right triangle because W is 90 degrees. VW is adjacent to V and UV is the hypotenuse. Adjacent any hypotenuse use the cosine function. 

Refer the image attached below for the image of the triangle.

plug in known values

The value of cos(72°) is 0.309

On substituting the above value in (1) we get,

Therefore, the required measure is 19.7 ft.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

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
