Parallelogram

Find the perimeter of the parallelogram, where base a = 8 cm, height v = 3 cm, and angle alpha = 35° is the magnitude of the angle at vertex A.

Correct result:

o =  26.461 cm

Solution:

a=8 cm v=3 cm α=35 ∘  sin⁡α=v:x  x=v/sin⁡α∘=v/sin⁡35∘ =3/sin⁡35∘ =3/0.573576=5.23034  o=2⋅ a+2⋅ x=2⋅ 8+2⋅ 5.2303=26.461 cm
