*100% CORRECT ANSWERS

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

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
