Answer:
20°
Step-by-step explanation:
Let x be the larger angle and y be the smaller angle.
Since they are complementary,
x+y = 90 => x=90-y
x+4y = 150
90-y+4y = 150
90 + 3y = 150
3y = 150-90
3y = 60
y = 20°
2,3 I think that’s the answer
3449995000 is what I got, I did 3.45x10^9 and then used that number and subtracted the answer from 0.5x10^4 to get the final answer, if that makes any sense.
