figure abcd is a parallelogram.

what are the measures of angles b and d?

∠b = 55°; ∠d = 55°
∠b = 55°; ∠d = 125°
∠b = 97°; ∠d = 97°
∠b = 83°; ∠d = 97°

The value of both the angles is 55 degrees. Thus, option (A) is correct.

ABCD is a parallelogram in which the measures of angle D and angle B are given.

The measure of angle D is (3n-5).

The measure of angle B is (2n+15).

Now, we know that the opposite angles of a parallelogram are always congruent to each other.

Therefore,

Thus, the value of n is 10.

Now,

Hence, the value of both the angles is 55 degrees. Thus, option (A) is correct.

i would need to see the dot plot : )

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
