#1.
Note that if you draw a broken line corresponding to the height of the parallelogram, you would form a right triangle in which the hypotenuse is 10 cm and one of the angles is 55 degrees.
We can actually solve for the height, which is equal to
10 * sin (55) = 8.19 cm
A of parallelogram = bh
A = 13 * 8.19
A = 106.5 cm^2
#2.
I'm not sure if this one requires a figure.
Anyway, hope this helps~ :3
1.Determine the area of a parallelogram in which 2 adjacent sides are 10cm and 13cm and the angle between them is 55 degrees?
2.If the area of triangle ABC is 5000m squared with a=150m and b=70m what are the two possible sizes of angle C?
