Answer:
<em>102°</em>
Step-by-step explanation:
(3x - 12)° + (2x + 2)° = 180°
5x - 10 = 180 ⇒ x = 38
m∠A = (3x - 12)°
<em>m∠A</em> = (3×38 - 12)° = <em>102°</em>
D=122 degrees, hope this helps!!
3*3=9
3 *-8i = -24i
8i *3 =24i
8i*-8i = -64i^2 or i^2 =-1. -64*-1=64
-24i + 24i =0
9+64= 73
Answer 73
Answer: 12x+27
