Answer:
246.979 ft
Step-by-step explanation:
When we draw our picture, we should be able to see that the angle of depression from the point of view is equal to the angle of elevation from the ground. We also know the height, and we are trying to find horizontal <em>x</em>. We must use tan∅ to solve:
tan39° = 200/x
xtan39° = 200
x = 200/tan39°
x = 246.979
Answer:
- b) 7r +r +2
- d) 3u +1 +7y
Step-by-step explanation:
Identify the variable in each term. If two or more terms have the same variable, they are "like" terms.*
1) Like terms are found in selection b. They are 7r and r.
__
2) The variables in selection d are u and y, not the same. Only unlike terms are found in selection d. (Selection b has variables x, b, x. The x-terms are like terms and can be combined.)
_____
* Strictly speaking, it is the constellation of variables you want to match. For example, terms 3xy, 4xy², and -5x²y all have variables x and y, but the powers of those variables don't match from term to term. For terms to be "like", the variables and their powers need to match.
