In a parallelogram, the diagonal forms angles of 63 and 45 degrees with the sides. find a sharp angle.

In order to find the acute angle, we first need to find the obtuse angle of the parallelogram. To do this, add 63 and 45: 45 + 63 = 108.

Now, since the sum of the two angles that are located on one side of the parallelogram is 180, we can find the acute angle: 180 – 108 = 72.

So our answer is 72.
