Remember that
![\sin(\theta) = \cos(90^\circ - \theta)](https://tex.z-dn.net/?f=%5Csin%28%5Ctheta%29%20%3D%20%5Ccos%2890%5E%5Ccirc%20-%20%5Ctheta%29)
Thus, we can solve for x.
x + 22 = 90 - (2x - 7)
x + 22 = 97 - 2x
3x + 22 = 97
3x = 75
x = 25
Answer:
Henry after 2 months: 250
His brother after 2 months: 220
Step-by-step explanation:
Henry started with $200 so add $25 twice (for 2 months) and get $250 dollars after 2 months.
His brother started with $150 so add $35 twice and get $220 dollars after 2 months
1.42 because you subtract 10 from the price
