A surveyor is 305 ft from the base of the new courthouse. Her angle-measuring device is 5 ft above the ground. The angle of elev
Charra [1.4K]

Answer:

279.62 feet

Step-by-step explanation:

We have a rectangle with 5ft x 305ft sides representing the area between your device and the base of the courthouse.

In addition to this we have an angle of 42 °

The height would come being the length of the opposite side of this triangle.

We know that:

tan (° A) = opposite / adjacent

Adjacent side is 305 ft and ° A is 42 °

Solved for opposite:

Opposite = adjacent * tan (° A)

Opposite = 305 * tan (42) = 274.62 feet

We must add 5 feet to this result and we are left with:

274.62 + 5 = 279.62

It means that the height is 279.62 feet

halfway through the fourth year , harrys collection contains 400 pennies. study the graph provided at the beginning of this acti
elixir [45]

Answer:

The coordinates of the point is (3,5 , 400)

Step-by-step explanation:

The question is incomplete as the graph is not given in the question. Lets complete the question first. I have attached the graph related to this question below.

We can see in the graph that x-axis represents the years while the y-axis represents the pennies collected by Harry.

We have to find the coordinates of the point where he is able to collect 400 pennies.

As y-axis represents pennies, and the point to be found is at 400 pennies, so the y-coordinates of the point is 400.

Harry collects 400 pennies when he is halfway through 4rth year, which means that he has been collecting for:

3 years + Half of 4rth year = 3.5 years.

As x-axis represents the year and the point to be found is at 3.5 years, so the x-coordinate of the point is 3.5.

So, the coordinates of the point is (3,5 , 400)

This point can be seen in the second graph
