Answer:
35
Step-by-step explanation:
To figure out how many revolutions Buddy goes in 1 minute, (60 seconds) we can use proportions
4 revolutions/11 seconds = x revolutions/60 seconds
When we cross multiply, (multiplying one numerator by the other denominator, and vice versa for the other numerator) we get
240 = 11x
divide both sides by 11 to get
21.81 = x
or 21 complete revolutions
All right triangles will always add up to 90 degrees unless stated otherwise.
Answer: the picture has no answer it's invalid but I will try:
X is a 90 degree angle other than that I can't do anything
