The two lines with arrows are parallel, which means angles A and B are supplementary.
So we have
A + B = 180º
(6<em>x</em> - 35)º + (3<em>x</em> + 53)º = 180º
(9<em>x</em> + 18)º = 180º
(9<em>x</em>)º = 162º
<em>x</em> = 18
This means angle A has measure
A = (6<em>x</em> - 35)º = 73º
Answer:

b) (4, -5)
Step-by-step explanation:
Just reverse the signs or use desmos as a better example.
Answer:
84
Step-by-step explanation:
The mean is calculated as
mean =
, then
= 21 ( multiply both sides by 4 )
sum = 84
