April saves $146 a month for college.
a. about how much money will she have after 3 years?
b. will your estimate be lower or higher than the actual amount april will save? how do you know?

a. 5400

b. higher

Step-by-step explanation:

a. 3 yrs = 36 m

$146 ≈ $ 150

36 m * $150 / m = $5400

b. My estimate will probably be higher because I rounded up.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
