Answer:

∠ = 80°

Step-by-step explanation:

The sum of the interior angles of a quadrilateral = 360°

Subtract the sum of the 3 given angles from 360 for ∠C

∠C = 360° - (90 + 112 + 78 )° = 360° - 280° = 80°

Which is equivalent to the complex number i^32?

Ksivusya [100]

Answer:

where i^2 = -1 (minus one)

So, i^2 = -1

i^4 = (i^2)^2 = (-1)^2 = -1 X-1 = 1

like ;

i^32 = (i^2)^16 = (-1)^16 = -1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X

= 1
