Ok if you would to take away 3 it would increase the mean median and mode
AB = 24
BC = 45
AC = 51
cos C = adjacent / hypotenuse
cos C = BC / AC
cos C = 45/51
Step 1
<u>Find the slope of the line PQ</u>
we know that
the formula to calculate the slope between two points is equal to
we have
substitute the values
Step 2
Find the equation of the line that passes through point R ans is parallel to line PQ
we know that
If two lines are parallel, then their slopes are the same
The equation of the line into point-slope form is equal to
we have
substitute the values
Step 3
we know that
The point on the y-axis that is on the line is equal to the y-intercept of the line
The y-intercept is the value of y when the value of x is equal to zero
so
For find the value of y in the linear equation
The point that is on the y-axis is
therefore
<u>the answer is the option A</u>
see the attached figure to better understand the problem
Answer:
One triangle can be constructed.
Step-by-step explanation:
Recap that all the interior angles in a triangle add up to 180. With the given measurements of the angles, 70 plus 80 plus 30 equals 180. Each triangle has the sum of 180 degrees. Therefore, there can only be one triangle that can be constructed. I think you were suppose to put can, not can't. Hope this helps!
D=distance traveled one way
t=d/s
d/20 + d/30 = 12
3d+2d=60(20)
5d=720
d=720/5 = 144 mi one way
144/20 = 7.2 hrs at 20 mph
144/30 = 4.8 hrs at 30 mph
