Beth gets on the elevator at the sixth floor. She rides up three floors to meet Doris. They ride down seven floors to meet Julio
Stella [2.4K]

Answer:

4

Step-by-step explanation:

Firstly, she gets on the elevator at the 6th floor. This means she was originally at the 6th floor.

She then stopped in the next three floors. This means she got off at floor 9 where we had Doris.

From Doris, she has to take 7 floors down to meet Julio. This means she went back to floor 2.

Now since her starting position was 6 and she is presently at the 2nd floor, this means she is four floors away from her starting position on the sixth floor.

Remember
if |a|=b then assume a=b and a=-b
divide boths ides by -3

|2x+6|=4
assume
2x+6=4 and 2x+6=-4
minus 6 both sides
2x=-2 and 2x=-10
divide by 2
x=-1 and x=-5

The angle of elevation from Nathan to a lighthouse is 74°.
Natalka [10]

Answer:

Nathan is 36.3910059 ft from the base of the lighthouse.

Step-by-step explanation:

So to find the base, you have to find the tan (both legs) of the right triangle that the lighthouse makes. The angle of Nathan to the lighthouse is 74° so to find the distances, you have to do the tan(72) = opp/adj

The opposite is 112, and we have to find the adjacent.

tan(72) = 112/adj

3.07768354 = 112/adj

adj = 112/3.07768354

adj = 36.3910059
