Answer:
You will need to convert to degrees when you are taking a right-triangle approach to trigonometry. In other words, if you are not utilizing aspects of the unit circle, you should convert to degrees. The opposite would go for radians. When you are taking a unit circle approach, convert degrees to radians.

The length of AD in the parallelogram is 143 cm.
<h3>How to find the side of a parallelogram?</h3>
A parallelogram is a quadrilateral with opposite sides parallel to each other. The opposite angles of a parallelogram are equal. Two adjacent or consecutive angles of a parallelogram are supplementary.
Hence,
2x + 72 + 2x - 20 = 180
4x + 52 = 180
4x = 180 - 52
4x = 128
divide both sides by 4
4x / 4 = 128 / 4
x = 32
Therefore,
∠A = 2(32) + 72 = 64 + 72 = 136 degrees
z = 136°
Therefore,
AC = BC = BD = AD
AC = z + 7
AC = 136 + 7
AC = 143 cm
Hence,
AD = 143 cm
