Answer:
Hey there!
<u>What we know:</u>
- The three triangles (two smaller ones and one larger one, are all right triangles)
- Measure of angle A is 42 degrees.
- Measure of angle C is 58 degrees.
- AC is 65 m.
<u>What we would like to know:</u>
First, let's find AB.
Sine 58= AB/65
Solving for AB, we see that it is about 55.12 m.
Next, let's find BD.
Sine 42= BD/55.12
Solving for BD, we see that it is about 36.88 m.
Let me know if this helps :)
1/5(6+3+1)^2

1/5 x 100
answer: 20
Answer:
Cylinder. The explanation is not very exact, more intuition and whatnot, so let me know if there was anything you did not understand.
Step-by-step explanation:
This is assuming the rectangle has its sides parallel with the x and y axes.
Let's try to eliminate them one by one. A cone does not seem likely since it has slanted sides, and spinning the two straight sides will keep the sides straight. This can be used for the pyramid as well. Let me know if this doesn't make sense though.
Now for me I would imagine that rectangle being a sheet of paper, or metal. if you set that sheet atop some dirt or something and then rotated it, what shape would be drawn into the material? It would be a circle. So we know the 3d shapewill have a base of a circle, which leaves us with a cylinder. Again, let me know if this method did not make sense.
The actual pen part is 3.5 inches, but with the cap it is about 5 inches
also a paper clip is about 4 cm
.004 = 4 / 1000
and 3.42 = 342/100
All you have to do is look at the place that it's in and write the number on top
Ex. 0.004 is in the thousandths place 4/1000
Ex. 3.42 is in the hundredths place 342/100 or 3 42/100
Hope This Helps! :)
