Answer:
14. C) 136°
15. C) 40°
Step-by-step explanation:
Inscribed angles are half the measure of the arc they intercept. For an inscribed quadrilateral, this means opposite angles are supplementary.
__
14) ∠H +∠W = 180°
34x +55x +2 = 180
89x = 178 . . . . . . . . . subtract 2
x = 2 . . . . . . . . . . . . . divide by 89
arc VX = 2(34x) = 68(2) = 136 . . . degrees
__
15) The sum of angles in the triangle is 180°.
? + 80° + (120°/2) = 180°
? = 40° . . . . . . . . . . subtract 140°
Z=16 because if you reverse it and go 13+3=z you get 16

in steps
Step-by-step explanation:
If it is a fair roulette, the probability to land on RED should be the same no matter what results are in the previous spin
a) 18/38
b) 18/38
c) Yes, I'm confident of the answers. Because it's fair and there is no change of RED numbers.
The 3rd one. (where the round part of the graph is at 0, 0) because that is where the y axis meets
First, let's convert the mixed fraction into an improper fraction (trust me, mixed fraction are pretty much the worst things to deal with, especially with higher level math):


Then, to subtract, since you need a common denominator, I would multiply the second fraction by 2 to get:

Now that we have a common denominator, we are ready to subtract:

Since that's the most simplified form, and you have been asked the question in a mixed fraction form, let's convert that to a mixed fraction. The remainder of the numerator divided by the denominator is 1, and the quotient is 3. The denominator stays the same. So, this is what results:

And that's your answer:

Hope this all makes sense. If anything doesn't, feel free to tell me!
