Sets E and B are defined as follows
E= {-2, -1, 3, 4, 7, 8}
B= {0, 1, 3, 8}

Find the intersection of E and B
Find the union of E and B

Intersection is what they both have in common.

In this case intersection of E and B is 3 and 8.

While the union is both of them added together.

Hope this helps

Step-by-step explanation:

104 degrees

Step-by-step explanation:

Since this is an isosceles triangle, two of the angles are congruent.

Angle NOP = 104 degrees

Angle NOP is congruent to angle LMN

Angle LMN = 104 degrees
