Trapezoid angle difference

Trapezoid, gamma angle=121°, alpha angle=2 thirds of delta angle. Calculate the angle difference alpha, beta

Final Answer:

x =  13 °

Step-by-step explanation:

γ=121  α=32 δ  γ+β=180   β=180γ=180121=59   α+δ = 180   32 δ + δ = 180 (1+2/3)    δ = 180  δ=180/(1+2/3)=108   α=32 δ=32 108=32 108=3216=72   x=αβ=7259=13
