Trapezoid 82216

Given is an isosceles trapezoid ABCD with bases 10 cm and 14 cm. The height of the trapezoid is 6 cm. Determine the interior angles of the trapezoid.

Correct answer:

α =  71.5651 °
β =  71.5651 °
γ =  108.4349 °
δ =  108.4349 °

Step-by-step explanation:

a=14 cm c=10 cm h=6 cm  x=2ac=21410=2 cm  tan α = h:x  α1=arctan(h/x)=arctan(6/2)1.249 α=α1  °=α1 π180   °=1.249 π180   °=71.565  °=71.5651=71°3354"
