As you see this is a right angle, so the sum of the two angles = 90°
So,
(x + 42) + 3x = 90°
Remove the parentheses:
x + 42 + 3x = 90
Combine like terms:
4x + 42 = 90
Subtract 42 on both sides:
4x = 48
Divide 4 on both sides:
x = 12

Answer:
$3838
Step-by-step explanation:
The mean of the given numbers is their sum divided by the number of them:
mean = (3000 +3500 +4000 +4500 +3000 +3500 +4204 +5000)/8
= 30704/8 = 3838
If Jim is using this mean for his forecast, then his forecasted sales is $3838.
