Answer:
70 degrees
Step-by-step explanation:
x = angle
180 - x = it's supplement
90 - x = it's compliment
(180 - x) - 4(90 - x) = 30
180 - x - 360 + 4x = 30
reducing
3x = 210
x = 70
Answer:
90
Step-by-step explanation:
There are 10 red candies, 18 green candies, 9 yellow candies, and 13 brown candies.
10 + 18 + 9 + 13 = 50.
There is a total of 50 candies. Out of the 50 candies, 18 are green.
You have to get to 250 .That means you do 
250 divided by 50 = 5.
18 x 5 = 90.
Therefore, she can expect 90 green candies
Equate the real and imaginary parts independently to find x and y.
Real part: -4=x, so x=-4
Imag. part yi=3i, so y=3
