Answer:
L ⊥ N
Step-by-step explanation:
Since M and N are perpendicular, and L is parallel to M, anything that's perpendicular to M is also perpendicular to L. In fact, since we have parallel lines, we now have many sets of congruent angles, but the only ones we know the actual measurements of are the right angles from the perpendicular lines.

y=66 and x=24
Step-by-step explanation:
Answer:
-276
Step-by-step explanation:
We'll use the method of cofactors. Use the coefficient +6 for
9 2
8 10
This gives you one third of the solution: 6 {(9)·(10) - (8)(2) }, or 444.
Next, use the coefficient 9, taking care to change the sign to -9 as follows:
9 1
-9 | | = -9(90 - 8) = -9(82) = -738
8 10
Finally with +2 as y our coefficient, evaluate the cofactor
9 1
9 2
ending up with
+2(18-9) = +2(9) = 18
Finally add these three results together:
+444 - 738 + 18 = -276
This, the determinant, D, is -276 (the fourth answer choice)
Use the pythagorean theorem. You should come out with C. Hope this helps!
