What is unique about finding the missing angles in Parallelograms

i dont know if there is supposed to be a picture in this one i found this for you

Step-by-step explanation:

The great thing about parallelograms is that the two consecutive angles must be supplementary. So we do not need to use the other angles in the figure. Recall that supplementary angles have a sum of 180°. Here we can see that if the missing angle is 129° that the sum of all four angles would be 360°.

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.

option d
