If angles are complementary, they add up to 90 whereas when they are supplementary, the add up to 180. So now let's focus on this problem. It says angle 1 and 2 are complementary. Therefore;
angle 1 + angle 2 =90
x+(3x+30)=90
x+3x+30=90
4x+30=90
-30 -30
4x=60
4/4x=60/4
x=15
Therefore, the value of x is 15

Answer:
48/37 + (8/37)i.
Step-by-step explanation:
8 / (6 - i)
We multiply top and bottom of the fraction by the conjugate of 6 - i , which is 6 + [email protected]
= 8*(6 + i) / (6 - i)(6 + i)
= 48 + 8i / (36 + 6i - 6i - i^2)
= 48 + 8i / (36 - (-1))
= 48 + 8i / 37
= 48/37 + (8/37)i.
