HELP!!!!!!!!! I’m almost done

balandron [24]

Alright, we're in the home stretch here :) All you need to remember is that i² = -1. Otherwise, it is the same as FOIL

(3-2i)(1+7i)

3-2i+21i-14i² ← Replace the i² with -1, then simplify like numbers

3+19i+14

17+19i or C

suppose a triangle has two sides of length 2 and 3 and that the angle between these two sides is 60. what is the length of the t

Answer:

√7 ≈ 2.646

Step-by-step explanation:

The law of cosines is applicable. It tells you ...

c² = a² + b² - 2ab·cos(C) . . . . . where a, b, c are triangle side lengths, and angle C is opposite side c.

Filling in the given information, you have ...

c² = 2² + 3² - 2·2·3·cos(60°) = 4 + 9 - 12·(1/2) = 7

c = √7 ≈ 2.646

The length of the third side is √7, about 2.646 units.
