Simplify:
(8 - 5i) - (-2 +3i)

Step-by-step explanation:

(8-5i)(2-3i)

using FOIL,

16-34i+15i squared?

here the number -5 is all of the following except a rational number.

step-by-step explanation:

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
