Lets say we represent the amount of time she could ski.
So it would be x = the amount of time she skis
And 5x would represent how long it took her to climb
and she took 9 minutes to climb.
So what we would do first is put it in a equation like this
x + 5x = 9
Now we have 6x = 9
Divide 9 by 6x, and we get x = 15
So multiply 1.5 by 5 and the answer would be 7.5
Hopefully this helped. :)
Answer:
not letting u cheat but i will show u how its done
Step-by-step explanation:
180-134=x
0.16, just put a line over the six so it can show its repeating
You need to use the law of cosine:
B^2 = A^2 + C^2 - 2ACcos(b)
55^2 = 90^2 + 50^2 - 2(50)(90)cos(b)
0.841666 = cos(b)
b = 32.68
