Side length ttt is 6.436.436, point, 43 and sss is 5.395.395, point, 39. Given that \dfrac st \approx \tan(0.697) \approx \sin(0.994) \approx \cos(0.576) t s ≈tan(0.697)≈sin(0.994)≈cos(0.576)start fraction, s, divided by, t, end fraction, approximately equals, tangent, (, 0, point, 697, ), approximately equals, sine, (, 0, point, 994, ), approximately equals, cosine, (, 0, point, 576, ), approximately what is angle \betaβbeta in radians, to the nearest tenth?

A withdrawal from an account means taking money out of your account. That means whatever money you have in there becomes a smaller amount because you're subtracting money from the account.

So, to work out how much money Jan withdrew as a negative sum, you just have to look at how much she took out:

-25 - 45 - 75 = -$145

This means Jan took out $145 from her account, and we write it with a negative sign because it's money that's going to be taken away from whatever's in there.

The same thing applies to Julie:

-35 - 55 - 65 = -$155

Julie took out $155 from her account, so her withdrawals were -$155.

Therefore, your final answer for 24a. is -$145 and your answer for 24b. is -$155.
