Answer:

T = 500 - 10(40 ) where T is the total money put into the holiday dinner party fund.

Step-by-step explanation:

I solved it too. Using PEMDAS, multiply accordingly (use correct integers) then subtract to find T:

T = 500 - 400

T = 100

Given that sin(90 -5ϴ) = Cos(180 - ϴ), Find the value of ϴ

lilavasa [31]

Answer:

30°

Step-by-step explanation:

$\because \: \sin(90 \degree - \theta) = \cos \theta \\ \therefore \: \sin(90 \degree - 5 \theta) = \cos 5\theta....(1) \\ \\ \sin(90 \degree - 5 \theta) = \cos(180 \degree - \theta)...(2) \\ from \: (1) \: and \: (2) \\ \cos 5\theta = \cos(180 \degree - \theta) \\ 5 \theta = 180 \degree - \theta \\ 5 \theta + \theta= 180 \degree \\ 6\theta= 180 \degree \\ \theta = \frac{180 \degree}{6} \\ \\ \huge \red{ \boxed{\theta = 30 \degree}}$
