The pilot in a plane is cruising at 4 miles sees a tree. The angle of elevation from the base of the tree to the plane is 40°.
answer: $13,622.84
step-by-step explanation: check the picture for info and stats : )
the equation of the parallel line would be y = 2x + 9
step-by-step explanation:
to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2
since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.
y - y1 = m(x - x1)
y - 5 = 2(x + 2)
y - 5 = 2x + 4
y = 2x + 9
but which class are u may know that first
We have to find x.
We can use the trigonometric relations to find the value of x.
We know that, for a right triangle, the sine of an angle is equal to the quotient between the opposite side and the hypotenuse.
In this case, the opposite side of the angle is the height of the plane (4 mi) and the hypotenuse is x, so we can write:
the value of x is approximately 5.22 miles.
