Answer:
122
Step-by-step explanation:
The first thing to notice is that <EBC and <ABE form a straight line. This means they are a linear pair, also known as complementary. So, when they are added together they will equal 180 degrees. Therefore, to solve, set up and solve the algebraic equation, 180=58+x. When 58 is subtracted from both sides, you are left with x=122.
25 + 100i is correct because -5 squared is 25 and the the square root of -100 is 100i or 10i in its simplest form.

Answer:
a) 81
Step-by-step explanation:
Number of sides of the polygon = 6
Sum of angles of the polygon = ( n - 2) * 180
= (6 - 2) * 180
= 4 * 180
= 720
n = 720 - (110 + 108 + 143 + 122 + 156)
= 720 - 639
n = 81
