Question 1

The furthest angle of elevation to the top of the steeple was 20 degrees and the closest angle elevation to the church was 29 degrees. Each person is 1.7 meters tall from his feet to his eyeballs. In order to find the height of the church, what do we need to find first.

Measure of Angle ABC

Question 2

The furthest angle of elevation to the top of the steeple was 20 degrees and the closest angle elevation to the church was 29 degrees. Each person is 1.7 meters tall from his feet to his eyeballs. Find the measure of angle ACB. (Hint: Find measure of angle ABC first).

9 degrees

Question 3

Using the provided measures determine the measure of angle ACB.

72 degrees

Question 4

Using the provided measures determine the length of the segment AC.

7.1cm

Question 5

Using the provided measures determine the length of the segment AB.

10.9cm

Answer 2

Length of BD.

Explanation:

We know the value of angle CBD, and we know that for an angle x in a right triangle with hypotenuse h, non-hypotenuse side a adjacent to angle x, and side o opposite angle x, tan(x) = o/a. So:

tan(CBD) = height/BD

height = BD*tan(CBD)
