Question 318770: ABCD is an inscribed quadrilateral. Find the measures of angles A, B, C, D?
I cant get the picture, but i can describe it.
Inside the circe is a quadrilateral.
Quad. ABCD
Angle A is the lower left corner
Angle B Is the upper left corner
Angle C is the upper right corner
Angle D is lower right corner
Angle A= 2x+y
Angle B= 2y-10
Angle C= 80
Angle D= 3x

You can put this solution on YOUR website!
There's not enough information.
The sum of all of the angles equals 360.
2x%2By%2B2y-10%2B80%2B3x=360
5x%2B3y%2B70=360
5x%2B3y=290
You need to know something about the relationship of the angles.
If ABCD was a rhombus, parallelogram, square, or rectangle, you would know an additional relationship between x and y and be able to solve.
Right now you have 1 equation with 2 unknowns.
