If you post your efforts we are helped in our effort to help you.

i haven’t made any progress because i’m unsure of where to start. would i set the two given to each other as diagonal so bisect each other and then multiply the outcome to get the whole diagonal of AC?Can you post what you've tried, so we know where you're stuck?

i’m sorry. i’m really bad at Geometry, and i have to keep reading through everything

In a parallelogram, opposite angles are equal, and adjacent angles are supplementary. Based on that, can you proceed?i haven’t made any progress because i’m unsure of where to start. would i set the two given to each other as diagonal so bisect each other and then multiply the outcome to get the whole diagonal of AC?

@skybell17Opposite angles of a parallelogram have the same measure.
