Answer:
25 degrees
Step-by-step explanation:
Angles 4 and 6 are supplementary angles since they as same side interior angles for parallel lines cut by a transversal. This means angle 4 + angle 6 = 180. If angle 6 is 155 then angle 4 must be 25 degrees
Answer:
142 degrees
Step-by-step explanation:
As 38 degree and angle 7 form a linear pair, they are supplementary
Let the measure of angle 7 be x
Hence, x+38=180
x=180-38
x=142 degrees
The average height is
and

How to find the average height ?
Allen height is 
Terrel height is 
And we know that 
So Allen height is

And Terrel height is

Average of the Allen and Terrel height is

And average height in feet is
