First, the values of 2sqrt(3) or 3sqrt(3) are not even twice the length of the given base, 3.
Next, I would say that 6 is the better answer than 12, assuming that the triangle is”drawn-to-scale”.
Finally, I think the hypotenuse is 6.
Height of the kite is = 36 inches.
Width of the kite is = 30 inches
One of the ways to find the area is to draw a vertical line to break the kite into two equal triangles. Mark the base as 36 inches and height as 15 inches .
Now we will use the formula 
to find the area of each triangle. Then we will add both the areas to find the area of the kite.
Area of 1 triangle = 
= 270 square inches
Area of the 2nd triangle is also = 270 square inches
Hence, area of the kite = 270+270 = 540 square inches
No he did not because 20% of 250 is 50 and there are 90 students not 50 students!! Hope this helped you a lot !!!
The prisoners could do a pattern that could signal who has already been in the room. So for example, one light off, both lights off, one light on, both lights off. But with left and right lights to make the sequence last as long as possible. Then after that sequence to have the last one be the signal that everyone has been in there. I dunno this is tricky lol
