Question

Find The Missing Values Within The Parallelogram

(as seen in the picture below)

Answer 1

I will try to fill in some of the missing information in the next drawing, please tell me if I'm correct. (a = 5, b = 8, theta = 45 degrees. Find sides c, d, and phi.



Looking at the bottom triangle, with sides [x], b, and d:



Again, I don't know if the data I filled in so far is right. The answers should come out to be:

a = 5 (given), b = 8 (given), c = 12.07, d = 5.69, theta = 45 degrees (given), phi = 135 degrees.

In the pictures, I forgot to label phi as 135 degrees. (180-45) [degrees].
