Trapezoid 2520

Trapezoid with sides a = 10, b = 20, c = 25, d = 15. Calculate all internal angles.

Correct answer:

α =  96.3791 °
β =  131.8103 °
γ =  48.1897 °
δ =  83.6209 °

Step-by-step explanation:

α=18083.620898368163=96.3791=96°2245"
β=18048.189703979289=131.8103=131°4837"
γ=48.189703979289=48.1897=48°1123"
δ=83.620898368163=83.6209=83°3715"
