all 3 angles in a triangle need to equal 180 degrees
62 +73 = 135 degrees are known
180-135 = 45
so angle B = 45 degrees
Y = 3/4x -4
The slope is 3/4 since it is written in the form y =mx+b where m is the slope
We want a line that is parallel so it will have the same slope
We know the slope of the new line (3/4) and a point (-1,7)
So we can use the point slope form of the equation
y-y1 = m(x-x1)
y-7 = 3/4(x--1)
y-7=3/4(x+1)
That's what the graph should look like and I wrote the rest on there just incase you needed any other information.
48 students in group 2
43 students in group 1
So in total there are 91 students
7 students play the trump
And 20 play the trombone
Therefore it is known that 27 students play those two instruments in total
Because of this, Subtract 27 from 91 to get the num of students who doesn't play those instruments.
When you are finding the mode your looking for the number that shows up the most. In this the mode is 58.
