Answer:
A: <MKB, because of the isosceles triangle theorem. If two sides of a triangle are congruent, it is isosceles, so the angles opposite them are also congruent.
Step-by-step explanation:
I know that the answer for number 10 is the first option
Answer:
<em>3. x = 8</em>
<em>4. lines r and s</em>
Step-by-step explanation:
3.
The angles shown are same side interior angles, so they are supplementary. Their measures add to 180 deg.
5x + 10 + 130 = 180
5x + 140 = 180
5x = 40
x = 8
4.
Lines r and s are cut by a transversal, line l. Angles 3 and 6 are alternate interior angles. Lines r and s are parallel.
is the factored form of 
<em><u>Solution:</u></em>
We have to factor the given expression
We can use the algebraic identity to factor the given expression
Lets make the given expression in form of 
Now apply the algebraic property in above expression
Here, a = 2x and b = 3y
Therefore,
Thus the given expression is factored out
