Answer:

Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary, so ...
m∠A + m∠C = 180°
Substituting the given expressions, we have ...
(3x +6)° + (x+2)° = 180°
4x +8 = 180 . . . . . . collect terms, divide by °
x +2 = 45 . . . . . . . . divide by 4
3x +6 = 135 . . . . . . multiply by 3
This is the value of angle A in degrees, so ...
m∠A = 135°

Answer:

Step-by-step explanation:
y = 3 - xy
Let x = 1
y = 3 - (1)y
Expand brackets.
y = 3 - y
Add y to both sides.
2y = 3
Divide both sides by 2.
y = 3/2
