ANSWER
x=35°
EXPLANATION
The sine and cosine ratio are complementary trigonometric ratios.
This means that:
sin(A)°=cos(90-A)°
The given equation is:
sin(55)°=cos(x).
This implies that,
x=90-55
x=35°
So if there are twenty children and 6 have an average age of five, you could say their total age together is 30 years. The others (20-6) have an age of 8.
30+ (20-6)*8 = total age of every child at the library. From there divide by the number of children.
758, you go by the one's number first. 5 and up rounds up to 10, so we goto the next number 50, 5 rounds up to 10, so up from 50 goes to the next hundred. 800 is the nearest hundred.
