Hi,
Can someone tell me how I would find a) the length of side BC and
b) the angle B,on the sketch,
Thanks....
Hello, manich44!
Is there more information?
As given, the problem has no single solution.Code:D o * * * * * * * * A o 105.4° * * o C * * * * * * o B
We are given 3 sides and one angle of a quadrilateral.
This does not determine a unique quadrilateral.
Hello, manich44!
I'll give you the Game Plan.
The rest is up to you . . .
Code:D o 34.37 * : α * 37.62 * : * * : * A o 105.4°: o C * : * * : * * : * 41.4 * : * * θ: * * : β * *: * o B
