Based on the angle of inclination and the distance up the side of the mountain, the height of the top of the mountain is 2,619 m.
What is the height of the mountain?
The Sin formula can be used here.
For the first lift, the Sin formula shows:
Mountain height till first lift / Distance traveled = Sin (angle of inclination)
Mountain height / 2,200 = Sin 48°
Mountain height first lift = 2,200 x Sin 48°
The second lift:
Mountain height second lift = 1,500 x Sin 41°
The total height is:
= (2,200 x Sin 48°) + (1,500 x Sin 41°)
= 2,619 meters

Answer:
can you explain more
Step-by-step explanation:
Answer:
FOIL IT:
First multiply the first terms in each parenthesis.
Outside is next. You multiply the terms on the outer edges of each parenthesis.
Inside is next. Multiply the terms on the inside edge of each parenthesis.
Last: Multiply last terms in each parenthesis.
YOU GET:
3x^2 - 2x - 8
Step-by-step explanation:
I will call the angle A.
we need to use cos, sine, and tangent here
cosine= adjacent over hypotenuse
sine = opposite over hypotenuse
tangent = opposite over adjacent
the angle A has x as the hypotenuse
and y is adjacent to the angle
cosine will be used
cos(A)= adjacent/hypotenuse
cos(A)= 5/x
get x alone by using opposite signs
x and 5 are dividing. the opposite of division is multiplication , but in order to cancel 5 from the right side i need to multiply the reciprocal. 5 is on top, needs to be on bottom to cancel out
cos(A)*(1/5)= 5*(1/5x)
cos(A)/5=(1/x)
flip both sides to get x on top
(5/cos(A))=x
use calculator
and make sue it is in degrees
x=5.8 cm
RU is a line which needs to equal 180 degrees. This means angle VSR + VSU needs to equal 180.
VSU = 100
VSR = 180 - 100 = 80
Answer: VSR = 80
