Let the width be x, then the length is x + 12.
Area = length x width = x(x + 12) = 589
Solving the quadratic equation, we have that
x = 19 feet
i.e. the width is 19 feet.
Answer:
m<ACD = 90
m<CDB = 126
m<EDB = 54
m<CDE = 180
Step-by-step explanation:
Well you have the right girl! *In honors geometry you can trust me!
Ok first thing...We already know
B = 54
A = 90
D = 54 (It's the Alternate interior angle of B)
C = 90
m<ACD = 90 (C = 90)
m<CDB = 126 (D = 54 ------> 180-54= 126)
m<EDB = 54 (Alternate Interior angle of B)
m<CDE = 180 (It is a straight line)
Hope this helps ya!!
Supplementary angles sum up to 180 degrees.
2x - 4 + 2x + 4 = 180
4x = 180
x = 45
Therefore,
m<9 = 2(45) - 4 = 90 - 4 = 86 degrees
m<10 = 2x + 4 = 90 + 4 = 94 degrees.
The answer is:
14.875
Hope this helps
