1. C                3. A                      4. A

Step-by-step explanation:

1. The interior angles of a triangle will always add up to be 180º. so when you solve 52+76+x=180, you find that x=52, which means that N and L are equivalent which means that MN=ML.

3. This triangle is an isosceles triangle so the length of the left side of the triangle will be the same as the right side.

4. The vertex has to at least be 42 more than 3 TIMES the other angles, so A is the only reasonable answer

i can only answer that one for now, i have to go, but i can answer it again later by editing this:)

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
