Let point A be 
and point B 
Use the point-slope formula and whichever point you want as 
, in this case I'll use
Step-by-step explanation:
192 / 24 = 8
Since 8 is a whole number, 8 classes per grade is enough to accommodate the 192 students in the grade.
The answer is 8.
Answer:
A
Step-by-step explanation:
You divide the diameter by 2 to get radius. So 5÷2=2.5
So then you multiply 2.5 by pi aka 3.14 so 2.5x3.14=7.85 So we rounds 7.85 to 7.9
The little lines through the two sides mean they are the same length.
When the two sides are the same length the 2 corresponding angles are also the same, so Angle A and Angle B are both 34 degrees.
The three inside angles of a triangle equal 180, so angle C = 180 - 68 = 112
Angle C is given as 4y, so 4y = 112
Divide both sides by 4:
y = 112 / 4
y = 28
