Quadrilateral ABCD is inscribed in circle O.
2 answers:
Opposite angle of a quadrilateral add up to 180 degrees.
This means Angle A plus Angle C equal 180.
We can solve for X using that, then solve for Angle B.
2x-7 + x +4 = 180
Simplify:
3x -3 = 180
Add 3 to each side:
3x = 183
Divide both sides by 3:
x = 183 /3
x = 61
Now we know x, replace x with 61 in the equation for Angle B:
Angle B = 2x+3 = 2(61) +3 = 122 +3 = 125 degrees.
I encourage everyone taking this test to take my word that it's 125.

You just put two numbers that you can multiply to get the number and when you came divide anything else in the number then you circle it and that's one of the numbers
