Someone please help me with these questions
lukranit [14]

Answer:

8) x = 5.41

9) x = 45

10) x = 2.25

Step-by-step explanation:

8) 17/15 = 10/(2x-2)

150 = 34x - 34

reduce:

34x = 184

x = 5.41

9) 6/16 = (x-12)/(2x-2)

16x - 192 = 12x - 12

reduce:

4x = 180

x = 45

10) (x-9)/15 = (2x-9)/10

10x - 90 = 30x - 135

reduce:

20x = 45

x = 2.25

You are hiking and are trying to determine how far away the nearest cabin is which happens to be due north from your current pos
elixir [45]

Answer:

469.60 yards far away is the cabin to the nearest​ yard

Step-by-step explanation:

given data

walks = 215 yards

bearing on the cabin =  N 24.6 degrees E

solution

we know here when 2 line are parallel then opposite angle are equal

so here \angle DAC =

and now we take here triangle ABC

so here we can say

tan (24.6 ) = \frac{AB}{BC}

so here BC will be

BC = \frac{Ab}{tan(24.6)}  

put here value and we get

BC = \frac{215}{tan(24.6)}

solve it we get

BC = 469.60 yards
