85$ left

Step-by-step explanation:

You can set up an equation like so:

225 (how much she has to start)

20 (how much she takes out each week)

w (how many weeks she took money out)

d (how much she has remaining)

225-20w=d

Substitute 7 in for w so you can find out how much she has left after 7 weeks:

225-20(7)=d

Then simplify:

225-140=d

85=d

85$ is your answer

Hope this helps!

(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

i belive those are the ones that are under 90 degreese.
