What is measure of angle R?

Anna [14]

To find an angle you need to use trig ratios (tan, sin, and cos).

In this case to find ∠R you would need to use sin or cos because both of the legs are not across or adjacent to it.

To find ∠R you would need to do the "opposite" formula which would be (for sin) 5/13 <span>≈ 0.38.. asin = 22.26</span>

Find the distance between the two points (-10,3) and (0,27)

crimeas [40]

Answer:

26 units

Step-by-step explanation:

$\boxed{distance \: between \: 2 \: points = \sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} } }$

Using the formula above,

distance between (-10, 3) and (0, 27)

$= \sqrt{ {( - 10 - 0)}^{2} + {(3 - 27)}^{2} }$

$= \sqrt{ {10}^{2} + ( - 24) {}^{2} }$

$= \sqrt{100 + 576}$

$= \sqrt{676}$

= 26 units

You are a contractor who is installing a new wooden fence for a customer. The dimensions of the fence are 20 feet long and 6 fee

ahrayia [7]

Answer:

$132

Step-by-step explanation:

First we need to find the total number of woods required. This would be total area of fence divided by area of each wood. Remember to convert inch into feet.

$\frac{area of fence}{area of wood} \\=\frac{20 * 6}{6 * 0.3333} \\= 60 woods plank$

Now we know the total number of planks, we need to find what is the cost of each plank. We know that one wood plank area is 2 sq. ft ( 6*0.33333). Therefore, the cost of each plank is = cost per area(sq.ft) multiply by total area (sq. ft).

cost per plank = 2 * $1.10 =$2.20.

We have total planks = 60 units and we have cost per plank = $2.20.

So, we can find total cost as 60*2.20= $132
