Step-by-step explanation:

Given that,

Hypotenuse, H = 10

The angle of elevation is 44°

We know that,

\sin\theta=\dfrac{P}{H}

P is perpendicular

P=H\times \sin\theta\\\\P=10\times \sin(44)\\\\P=6.94

Using Pythagoras theorem,

RT=\sqrt{10^2-6.94^2}\\\\RT=7.1

The sum of angle of a triangle is equal to 180.

44+90+S=180

S=180-134

S = 46°

Hence, this is the required solution.

What is the perimeter and area of 9ft width and 8ft Long?
Sever21 [200]

Answer:

Perimeter = 34ft Area = 72ft squared

Step-by-step explanation:

The perimeter of an object is all of it's sides combined. Because you stated two values, I assumed your shape is a rectangle. So the perimeter would be:

8 + 8 + 9 + 9 = 34

The area is length times width, so:

8 x 9 = 72

Because it is area, the units are squared.

A sofa regularly sells for 860. The sale price is 670.80. Find the percent decrease of the sale price from the regular price
andre [41]

Answer:

-22%

Step-by-step explanation:

The percent decrease can be found by subtracting the original amount from the sale price. Divide the result by the original price and multiplying the decimal by 100 for the percent.

670.80 - 860 = -189.2

-189.2/860 = -0.22

-0.22*100 = -22%

A rectangular flowerbed at a city park has an area of 126 square meters.the width of the flowerbed is 3 meters.what is the perim
Alona [7]

First we need to find the length. So we do 126/3 to get 42. The length is 42. Now to find perimeter we do 2(42)+2(3) or 42+42+3+3.

Both ways are right ways. The perimeter is 90 meters.

Hope that helps!!
