In ΔABC is an oblique triangle with sides a,b and c , then asinA=bsinB=csinC . To use the Law of Sines you need to know either two angles and one side of the triangle (AAS or ASA) or two sides and an angle opposite one of them (SSA).

The diagram shows a scale drawing of a playground the scale of the drawing is 1:500 work out the perimeter of the real playgroun
liraira [26]

Answer:

Check Explanation

Step-by-step explanation:

The complete question plus diagram is presented in the attached image to this solution.

From the attached image, the dimensions of the playground drawn will be a bit variable now as zooming and some editing might have tampered with the original intended dimensions to be measured.

But still, let us assume that on measuring the rectangular playground shown, we obtain approximately that the length is 4.5 cm and the breadth is 2 cm.

The scale to convert to real life is 1;500 indicating that

1 cm on the drawing = 500 cm lenght units of the real playground.

So,

4.5 cm on the drawing = 4.5 × 500 = 2250 cm of the playground

2 cm on the drawing = 2 × 500 = 1000 cm of the playground.

Hence, the real life dimensions of the playground is 2250 cm by 1000 cm.

In meters, that is 2.25 m by 1 m

The perimeter of a rectangular figure is given as

Perimeter = 2(Length + Breadth)

= 2(2.25 + 1)

= 6.5 m

Hope this Helps!!!

Perimeter is 342 ft, length 99ft, what is the width
ehidna [41]
In formula, you take length * 2 + width *2 = perimeter 

2L + 2W = P

put in the numbers and

2 (99) +2W = 342

198 + 2W = 342

2W = 342 - 198 

im sure you can do the rest. PM me for additional help, Good luck!

There are 400 silver dollars in two bags. If 275 are in one bag, how many are in the other bag?
xz_007 [3.2K]
If there are 400 silver dollars in all, and there are 275 in one bag, to find the amount in the other bag, just subtract:

400-275=125

There are 125 in the other bag.
