Answer:
∠RST = 120°
Step-by-step explanation:
We assume the positions of the lines and angles will match the attached figure. The angle addition theorem gives a relation that can be solved for x, then for the value of angle RST.
∠RSU +∠UST = ∠RST
__
78° + (3x -12)° = (6x +12)° . . . . . substitute given values into the above
54 = 3x . . . . . . . . . . . . . . . . divide by °, subtract 3x+12
108 = 6x . . . . . . . . . . . multiply by 2
120° = (6x +12)° = ∠RST . . . . add 12, show units
The measure of angle RST is 120 degrees.

<em>Additional comment</em>
Note that we don't actually need to know the value of x (18) in this problem. We only need to know the value of 6x.
Here is my answer. I left the latter question in a. as I don't actually know the answer. Anyway, I hope this is helpful although not complete.
0, 1, 2, and 3 are greater than -1 and less than 4
Answer:
c
Step-by-step explanation:
theres only that one solution
I believe it is $7.30 You are not multiplying by $0.02 but simply adding on $0.02 until you get to the end of the year. Next, you would use the formula S (savings) = (n/2)(t + o), where (n) is the number of terms, number of day, (t) is the first term, and (o) is the original (years worth of money) term. So, (365/2)(0.02 + 7.3) = 1335.9.
Your answer is $1335.90.
