Answer:
15 and 108
Step-by-step explanation:
3*(30-25)=3*5=15
4*(12+15)=4*27=108
The length of the sky lift is 3.387.05 ft
Step-by-step explanation;
By an online search, i found that the sky lift
rises at an angle of 20.75 degrees.
Then we can think on a triangle rectangle, such
that:
One cathetus is 1200ft, this is the opposite
cathetus to the angle of 20.75°
The length of the ski lift would be the
hypotenuse of this triangle rectangle.
Then we can use the relationship:
Sin(a) = opposite cathetus/hypoteuse.
such that:
a = 20.75°
opposite cathetus=1200ft
then:
sin(20.75°) = 1200ft/hypotenuse
hypotenuse =1200ft/sin(20.759) =3.387.05 ft
The length of the sky lift is 3.387.05 ft
3x + 2x = 5x
-3 - 8 = -11
5x - 11 = 0
5x - 11 (+11) = 0 (+11)
5x = 11
5x/5 = 11/5
x = 11/5
hope this helps
