Calculate 48073

Calculate the area of the isosceles trapezoid ABCD if a = 14 cm, c = 8 cm, and the size of the angle DAB is 52 °.

Correct answer:

S =  42.2381 cm2

Step-by-step explanation:

a=14 cm c=8 cm α=52   x=(ac)/2=(148)/2=3 cm  tanα=v:x  v=x tanα=x tan52° =3 tan52° =3 1.279942=3.83982 cm S=2a+c v=214+8 3.8398=42.2381 cm2
