Answer:

(y + 7i)(y - 7i)

Step-by-step explanation:

It cannot be factored using real numbers, but consider

7i × - 7i

= -49i² and i² = - 1

= 49

The factoring as a difference of squares to obtain

y² + 49 = (y + 7i)(y - 7i)

Hello!

We can say that: x = 127°

The sum of the hexagon's internal angles is 720 °. So, just solve an equation:

112 + 133 + 128 + 100 + 120 + x = 720
593 + x = 720
x = 720 - 593
x = 127°

So, x = 127°.
