TS is the height of a building. PQR is a pole in front of the building. QT is a horizontal cable that supports the pole to the b

Iteru [2.4K]

Answer:

The answer is 65.75

Step-by-step explanation:

Since tq is perpendicular to PR then qtsr becomes square

Then

$qr = 30 \: \: \: \: \: and \: qt = 30 \\$

Since the triangle pqt is right angled

Then

$pq = qt \tan(50) = 30 \times \tan(50 ) = 35.75$

Then the height of the pole is equal to

$pq + qr = 35.75 + 30 = 65.75$

2. Find the area in square meters of the figure<br> below? Use 3.14 for.<br> 6m

Illusion [34]

Answer:

in order to find the area, we should break up the figure. you can see that in the image we have a quarter of a circle and a square. here are the areas for each of these shapes

square:

$area = {x}^{2}$

circle:

$area = \pi {r}^{2}$

but since we only have a quarter of this circle we need to divide the area by 4 so the formula becomes

$\frac{\pi {r}^{2} }{4}$

now we can plug in our numbers

we are given 6 m for our radius or length of square

the square will be (6)^2 = 36 m^2

now onto our circle

π(6)^2/4 = 28.26 m^2

now add these two shapes together to find the total area = 64.26 m^2

Solve the equation. Show your work. Check your answer.

Hitman42 [59]

4y+5=-31 you subtract 5 from both sides so you get 4y=-36 then you divide by 4 from both sides so you get y=-9 and to check you put -9 in for y and multiply 4 and -9 add 5 to get -31
