Answer:
I believe it is A because if you use the slope x it matches with the line.
20x2 = 40 in width
180-40= 140
140/2=70
70 inches
48 develop a fault out of the total built which is 2400 therefore
48/2400
If needs to be simplified then 1/50
Step-by-step explanation:
I can't see picture very well but as I see first angle is
-4x+5 and second is -13x+39 ( if it isn't, correct me)
sum of this angles is 180° because they are inner angles
(-4x+5) + (-13x+39) = 180
-4x+5 -13x+39=180
-17x+44=180
-17x = 180-44
-17x= 136
x= -8
angle -4x+5 will be:
-4*-8 + 5= 32+5= 37°
