Mathematics

First, set 2x+7 equal to 3x-7 since they are the same angle due to the parallel lines.

2x+7=3x-7
x=14

Then, since 2x+7 and 12y+1 equals 180, put it together to find y:

(2x+7)+(12y+1)=180
(2(14)+7)+(12y+1)=180
12y+1=145
12y=144
y=12

So, x=14 and y=12. Your answer should be C!

Find the perimeter of the polygon. Assume that lines which appear to be tangent are tangent. Round to the nearest tenth if neces
ikadub [295]

The perimeter of the polygon is 53.6 units.

Solution:

The reference image to the answer is attached below.

AP = 8, BQ = 7.8 and CR = 11

AP and AR are tangents to a circle from an external point A.

BP and BA are tangents to a circle from an external point B.

CQ and CR are tangents to a circle from an external point C.

<em>Tangents drawn from an external point to a circle are equal in length.</em>

⇒ AP = AR, BP = BQ and CQ = CR

AR = 8

BP = BQ

⇒ BP = 7.8

CQ = CR

⇒ CQ = 11

Perimeter of the polygon = AP + BP + BQ + CQ + CR + AR

                                          = 8 + 7.8 + 7.8 + 11 + 11 + 8

                                          = 53.6

The perimeter of the polygon is 53.6 units.

P(A)=25,P(B|A)=920,P(A∩B)=?
larisa [96]
Hi! Let me help you!
This problem is a Venn Diagram question. It is much easier to answer this question with the visual it usually comes with. However, we can employ logic to give this one a smart and logical answer.

What we have so far:
P(A) =  25. This means that the shaded area of A is equal to 25.
P(B/A) = 920. This means that area A subtracted 25 to the value of area B which resulted to 920.
P(B) = 945. How did I arrive with 945? Simple, I just added 25 to 920. Go and be a smart lad and find why I did that.

Solution:
Solving P(A∩B) is quite challenging because like I said, a visual is needed for us to give it a pefect answer. Employing logic and using what we have so far:

If P(A∩B) means A and B intersection, we can assume that it is simply as A + B. 

If that is the case, then we can simply pull out our P(A) and P(B), 25 and 945 respectively and add them:

P(A) + P(B) = P(A∩B)
P(A∩B) =  25 + 945
P(A∩B) = 970 <----- What we are looking for

Therefore, P(A∩B) = 970!

Geometry. What is the value of x?
Yuliya22 [10]
Given that the length's of the secant's are equal, it implies that the distance of a perpendicular bisector from the secant to the center of the circle will also be the same. This implies that the value of x will be given by:
x=16
