hello i have the following trapezoid bellow:

the angle of @ is suppose to be 10 and it is asking me for the smaller base of trapezoid a and larger base of trapezoid b and the height of the trapezoid c Any help would be appreciated. It looks like the left and right triangle of that trapezoid should have angles of 90, 80, and 10? But after that i'm not sure how to go about solving for a and b

Would i get b by doing sin10=b/8? and since it's a trapezoid wouldn't b be 3x that and a=b?

EDIT: this is what i have so far

a=(sin10=a/8) or a=b=(sin10=b/8)

b=3(sin10=b/8)

c=(sin80=c/8)
