Answer:
6.67 m/s
Step-by-step explanation:
You basically use the formula height*base/2 to find the area of the triangle. For instance, let's say a is your chosen base, which has a length of 7. You then use the pythagorean theorem of the right triangle (which is formed by splitting the triangle in half), which is a^2+b^2=c^2, and you substitute half your base for a and the other length (8) for c, which is the hypotenuse of the triangle. Note how this is all being done to find "b", which is the height of the triangle, which will then help you substitute all of your known values into the area formula of a triangle to answer your question. I'm not sure if b=141 degrees would have an impact on this question, but I hope this helped you in some way.
Answer:
Step-by-step explanation:
There are only two games basketball and baseball.
Any student who plays could play basketball or baseball.
Given that there are 
students in total.
Given that there are 
students who don't play any game at all.
So,there are 
students who play play some baseball or basketball.
The required probability is
