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
Answer:
I think that the answer is a
Step-by-step explanation:
1 is your answer its law of trig identises
1/4 or 0.25
Lets plug x and y into the equation. We now have 3/12, which would be equal to 1/4 or 0.25
