11.1.3 Quiz: Introduction to Trigonometry
Question 5 of 10
2 Points
Fill in the blank.
A surveyor measures the angle of elevation to a point on a mountain to be 12
• The point on the mountain is horizontally 5 miles away from the surveyor.
The vertical change in elevation from the point where the surveyor is standing
to the point on the mountain is_ miles. (Round your answer to the
nearest hundredth of a mile.)
Answer here

Vertical change in the elevation is 1.06 miles.

Step-by-step explanation:

Distance between the surveyor C and the point A on a mountain = 5 miles

Angle of elevation of the point A from surveyor = 12°

We have to calculate the vertical height AB of the point A from the surveyor.

tan C =

tan 12° =

tan 12° =

h = 5tan12°

h = 1.063 miles

h ≈ 1.06 miles

Therefore, vertical change in the elevation is 1.06 miles.

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
