HELPPP PLEASE DUE NOW

Mathematics
1 answer:
lidiya [134]4 years ago

The angles that are 105º and (13x + 66)º are the same amount.
105 = 13x + 66
Subtract 66 from each side
39 = 13x 
Divide each side by 13
3 = x 

Now for z. 
Since two equal angles equal 105º each, multiply it by 2 to get 210.
The whole thing is 360º. 
360 - 210 = 50 
Divide it by 2 to get one of the angles
50 / 2 = 25
z = 25º

Hope this helps!

Let event Aequalssubject is telling the truth and event Bequalspolygraph test indicates that the subject is lying. Use your own
wariber [46]

Answer:

P( B | A) will actually be the probability of the polygraph test being wrong.

Step-by-step explanation:

The event A represents the event that the subject is telling the truth.

The event B represents  the event when he fails the polygraph test, which is indicative of the fact that he is lying.

The notation P( B | A) describes the probability that the subject fails the polygraph test given that he is actually telling the truth.

So in retrospect P( B | A) will actually be the probability of the polygraph test being wrong.

Solve the simultaneous equations C^2+d^2=5 and 3c+4d=2
Naily [24]
If 3c+4d=2 then c=(2-4d)/3
And if you put that into the other equation
{\frac{2 - 4d}{3}}^{2}  +  {d}^{2}  = 5
Then you multiply everything by 3, getting

{(2 - 4d)}^{2}  + 3 {d}^{2}  = 15
And then

2 - 4d +  \sqrt{3} d =  \sqrt{15}
Leaving
d( \sqrt{3}  - 4) =  \sqrt{15}  - 2
I dont have a calc with me right now but you just pot this into the calculator:
d =  \frac{ \sqrt{15} - 2 }{ \sqrt{3}  - 4}
And when you get the number you insert it into the nest eqation to get c

c =  \frac{2 - 4d}{3}
So basically

c =  \frac{2 - 4 \frac{ \sqrt{15}  - 2}{ \sqrt{3}  - 4} }{3}
