Answer:
42 degrees.
Step-by-step explanation:
17. The angles x and 42 degrees are base angles of an isosceles triangle so they are congruent.
x = 42 degrees.
The missing angle would be :
90°[right angle] + 45° = 135
180 - 135 = 45°
I took 135 away from 180 because angles in a triangle always add up to 180°
What is the interquartile range of this data set 1,5, 12, 14, 29,45,48,61,72,84,96
Viefleur [7K]
There are 11 numbers
Lower quartile = 3rd number = 12
Upper quartile = 8th number = 72
Interquartile range = 72-12 = 60
Answer:
B is at the origin. D is on the x-axis.
Step-by-step explanation:
For a point to be at the origin, it lies at the intersection of both the x- axis and the y - axis. Both axes intersect at the origin. So, point B is at the origin.
For a point to be on the x - axis, its coordinate on the y- axis is zero. So, for a point on the x- axis with coordinate, x, it is the point (x,0) and it lies on the x axis. So, point D is on the x - axis.
For a point to be on the y - axis, its coordinate on the x - axis is zero. So, for a point on the y- axis with coordinate, y, it is the point (0,y) and it lies on the x axis. So, point A is on the y - axis.
The point C which is at (1,2) lies in the plane x-y since it has both x and y coordinates.
