Answer:
1+b/a
Step-by-step explanation:
To find the amount of a/b we have to solve the equation
(a+b)/a
a/a+b/a
a/a is one so
1+b/a
Angle D is equal to Angle B because AB and DE are parallel to each other.
AD is a straight line so the (2) 2x angles and 72 degrees need to equal 180.
Setting up the equation you have:
2x + 2x + 72 = 180
Simplify:
4x + 72 = 180
Subtract 72 from each side:
4x = 108
Divide both sides by 4:
x = 108 / 4
x = 27
I ended up with 7/20, but I don't believe it's right. Sorry.
