Answer:
xy=2
Step-by-step explanation
2x + 3y =12
First divide 2 on both sides of the equation, than divide 3 on both sides of the equation.
X+5+2x+3
=3x+8

Answer:
angle C = 78
angle D = 108
Step-by-step explanation:
the measure of angle A is 102
To find the measure of angle C
let Angle C be x
102 + x = 180 (linear pair)
x = 180 -102
x = 78
angle C = 78
angle B = 78 (vertically opposite angles are equal)
angle D = 108 (vertically opposite angles are equal)
