<span>The length of AC is 8 units
The angle CDB is 67°
Since ABCD is a rectangle, that means that all of the angles are 90 degrees and that line segment AB is parallel to line segment CD. The line segment BD is a diagonal of the rectangle. The line segment AC is also a diagonal of the rectangle so it has the same length as given for segment BD which is 8. The angle ABD is the angle between the horizontal line and the diagonal. The angle CDB is also the angle between a horizontal line and the diagonal. So it also has the same measurement so it too is 67°.</span>

I said 72/.97 and then I rounded to the nearest tenth.
Answer:
The correct answer is <u>D) -15, 15</u>
Step-by-step explanation:
(-)15^2 = 225
Therefore, x^2 = 225 = (-)15^2
No it’s not, because I’m the problem they share a common vortex but not a common line.
Answer:
The student whose marks between quarter grades & topic tests score has maximum proportionate deviation
Step-by-step explanation:
Percentage change shows the proportionate change in a value, from the initial point. Formula = ( Change / Old ) x 100
Percentage change in students' quarter grades from topic tests score =
[ ( Quarter topic test score - Topic test score ) / Topic Test score ] x 100
Eg : Quarter Grade = 80, Test score = 60.
Percentage change = [ (80 - 60)/ 60 ] x 100 = ( 20 / 60 ) x 100 = 33%
So, student who has this maximum proportionate or percentage deviation between quarter grades & topic tests score - that student change would be represented by the point farthest from 0 on a number line.
