Answer:
The height of the tree is about 30 feet.
Step-by-step explanation:
tan(55) = h/21
*21 *21
21*tan(55)=h
29.99=h
h=29.99=30 feet
Let x = the number of green apples, let 4x = the number of red apples
4x + x = 50 Set up the quation
5x = 50 Combine like terms
---- ---- Divide by 5 on both sides to get x alone
5 5
x = 10 green apples
4x = 4(10) = 40 red apples
40 - 10 = 30. Suzanne bought 30 more red apples than green apples.
By a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.
An equation says that two things are equal. It will have an equals sign (assuming you know what that is) like this:
7+2=10-1
What the equal says on the left, is equal to the answer on the right.
Basically, it's a statement saying "equals that"
I don't fully understand your question, but I hope it helped you at least a little.
(-6)-(+67)= -73
