4 is B.
5 is true.
6- Statement 3: NO and ON are the same line. They are congruent by the reflexive property (a line segment is a reflection of itself)
Statement 4: Shape MNO and shape PON are congruent by side-side-side since:
side PN = side MO
side MN = side PO
side NO = side ON
So the answer would be D
Hope that helps!
There's no such thing as the "length"of an angle.
But we know what you're getting at.
You have said that the angles are complementary. If two angles are
complementary, then their sum is 90 degrees, so we can take your
two angles and write:
<u>x</u> (one angle) plus <u>(2x + 12)</u> (the other one) <u>= 90 degrees
</u><u /> x + 2x + 12 = 90<u>
</u>Subtract 12 from each side: x + 2x = 78
Add the x's on the left side: 3x = 78
Divide each side by 3 : x = 26 degrees
One angle is 'x' = <em>26 degrees</em>
The other one is (2x + 12) = 52+12 = <em>64 degrees</em>
Answer:
67
Step-by-step explanation:
Mean is the average
Add up all the values and divide by the numbers there are.
In this case, divide by 9.
