Answer:
∠DCF = 129°
Step-by-step explanation:
We assume that line CE is between lines CD and CF.
The angle sum theorem applies:
∠DCF = ∠DCE +∠ECF
∠DCF = 75° +54°
∠DCF = 129°
Answer:
If two sides of a parallelogram are represented by the vectors, then the lengths of the diagonals of the parallelogram by the parallelogram law are |→d1| and |→d2|.
The mathematical representation for the length of the diagonals is
|→d1| = | →u + → v|
|→d1| = | →u - → v|
