Answer:
Step-by-step explanation:
Well we can simplify the numerator, by multiplying the 4 by the 6 and the m^3 and m^4 (add the exponents, explained in one of my previous answers I think)
This gives us the fraction:
We can now divide the m^7 by m^2 by subtracting the exponents, and the reason why this works, is you're simply cancelling out the m's, If we express this in expanded form we have the following fraction:
Since there is two m's in the denominator and there is also two (more than two) m's in the numerator, we can cancel those two m's out, and we get the fraction:
which can be simplified in exponent form as:
, now all we have to do is divide the 24 by the 3, to get 8
This gives us the answer:
Answer:
Option D is correct.
The measure of
Step-by-step explanation:
is isosceles and
and
are base angles.
Isosceles Triangle:
A triangle with two equal sides, and two congruent base angles that means the angles are equal
By the definition, the base angles are equal i.e,
Since, YZ bisects
Angle Bisector theorem: An angle bisector is a line or ray that divides an angle into two equal angles
then, or
Substitute the value of ;
The sum of measures of these three angles of triangle WXY is equal to the 180 degree.
In triangle WXY we have;
Substitute the value of and
in above formula:
