There are 42 kids in one classroom. They are all divided into 3 groups. How many kids will be in each group?
W= P / 2 - L
Width= Perimeter over 2 subtracted by length
Answer: draw them out dude
Explanation: TrY geometry
You can draw a diagram of the situation, representing it by a right triuangle.
In the right triangle the hypotenuse is the distance indicated by the radio signal, 1503 m, and the angle is 41°.
The opposed leg to 41° is the height of the ballon.
Then you can use the sine trigonometric function.
sine (41°) = opposed leg / hypotenuse = x / 1503 m => x = 1503m * sine(41°)
=> x = 986m.
Answer: 986m
Since it is an equilateral triangle, all of the sides are the same length.
So, x=14 :)
Hope this helps!
