Distributive Property
Step-by-step explanation:
They distributed the -3 to x and 4. In this case, to distribute the -3, you multiply it to each term.
-3 × x = -3x.
-3 × 4 = -12.
-3x - 12
The first one is:
y = 5-7=-2
(5, -2)
second one:
4 = x + 3
x =4-3=1
(1,4)
Answer=72°
In this case, since AB and CD are parallel lines, the angle with 72° and angle x are congruent. Therefore angle x is 72°
