Dhaulagiri is the 7th highest mountain in the world. Ms. Fink is walking through
the Hidden Valley, preparing for an ascent of the mountain. She looks up to the
mountain and measures the angle of elevation to be 47.3° and she knows she is
at an altitude of 4900m. She hikes 1000m closer to the mountain with no
elevation change and notes the angle of elevation to be 58.5°. How high above
sea level is Dhaulagiri?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4
