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

Correct answer:

o =  26.4607 cm

Step-by-step explanation:

a=8 cm v=3 cm α=35   sin α = v:x  x=v/sinα=v/sin35° =3/sin35° =3/0.573576=5.23034 cm  o=2 a+2 x=2 8+2 5.2303=26.4607 cm
