2 supplementary angles when added together need to equal 180 degrees.
Add:
3x-23 + 2x-12 = 180
Simplify:
5x -35 = 180
Add 35 to both sides:
5x = 215
Divide both sides by 5:
X = 43
Now replace x with 43 in the equation for angle b:
2(43) -12 = 86-12 = 74 degrees
Angle B = 74 degrees
Eighty three thousand four hundred and seventy nine
The characteristics of these geometric figures create:
1. Parallel lines are lines in the same plane that will never intersect and also if they are in different planes, those lines will never intersect too.
2. While perpendicular lines are two lines that will meet at a 90-degree angle or right angle.
I’m assuming you want to work out the area
area = length x width
area = 10 x 8
area = 80 inches^2
Answer: 
Step-by-step explanation:
Let 
denotes the average braking distance for a population of small car.
Given : It is advertised that the average braking distance for a small car traveling at 65 miles per hour equals 120 feet.
i.e. 
Objective of test : Whether the statement made in the advertisement is false
i.e. 
Since '=' signs is contained by Null hypothesis and alternative hypothesis is against it.
So the null and the alternative hypotheses for the test will be:
