Line g is NOT parallel to line h. Angle 2 measures 75 degrees. Angle 4 measures 85 degrees. Question 1A: What is the measurement of Angle 1? *
g
1/2
8/ 3
h
7/4
6/5

H    

[sorry, can't draw in the application.]

1. Slope from H to B is 25

   Slope from H to A is 77

   therefore the angle AHB is 77-25 = 52 degrees

2. the angle HBA is 25+90 = 115 degrees [draw a line parallel to the ground through B. Alternating interior angle will be 25 plus the right angle going vertical.]

3. Therefore angle HAB (at the top) is 180 - 52 - 115 = 13 degrees

Using Law of Sines

sin(HAB)      sin(AHB)

 =

length a       length h

or, sin(13)      sin(52)

     =  

        50             h

solve for h = approx 175 feet
