Answer:
2,4,3,1
Step-by-step explanation:
We could go into calculating the area of the circle using the information we have, but I think this question just wants us to eyeball it.
Does each quadrant of the circle look like it's taking up more than half, or less than half of each square?
Probably looks like more doesn't it.
Which means that there's at least more than 2 square units being taken up by this square.
It also means that it's taking up less than 4 square units, since each square is not being filled up.
Is it more or less than 3?
It's really depends on the perspective on whoever looks at it, but to me personally, it looks like it's more than 3 units long.
Hope this helps.
頑張って!
Answer:
1011.05
Step-by-step explanation:
Let's use 3 as an example.
The angle of depression is the one directly under the ballon.
You also know that the 53 degree angle is part of a 90 degree angle.
so the angle inside the triangle directly under the balloon is 37 degrees.
You know the angle and you know the side from the balloon to the ground is 1680. This is the hypotenuse of the triangle.
So which trig function could you use to determine how high the balloon is from the ground?
SOH CAH TOA
cos 37 = a/1680
a = 1341.71
