ISO trapezium

Calculate the area of an isosceles trapezoid with base 50 long, leg 12 long, and with the angle between the base and leg 70 degrees.

Final Answer:

S =  517.53

Step-by-step explanation:

a=50 r=12 α=70   h=r sin(α)=12 sin(70°)11.2763 x=r cos(α)=12 cos(70°)4.1042 c=a2 x=502 4.104241.7915  S=2a+c h=250+41.7915 11.2763=517.53
