If ac is parallel to df, what is the measure, in degrees, of ∠abd

ABD = 28°

Step-by-step explanation:

Since the lines are parallel this means that angle BEF and angle ABE are equal because they are alternate interior angles. We are given a right angle which measures 90°. This means we can do 118°-90° to give us angle ABD. This means that angle ABD is 28°.

The equivalent quarterly rate is about 2.178%.

 (1 +r)^4 -1 = 0.09

  (1 +r)^4 = 1.09 . . . . . add 1

 1 +r = 1.09^(1/4) . . . . . take the 4th root

 r = 1.09^(1/4) -1 ≈ 0.0217782.
