I'm having a hard time with my geometry class. Please help me!
Vedmedyk [2.9K]

Answer:

Angle EFG = 82 degrees; Angle GFH = 98 degrees

Step-by-step explanation:

Linear pairs are angles that are placed side by side. When you add them together, you get 180 degrees.

Show work:

3n + 22 + 4n + 18 = 180

7n + 40 = 180

7n = 140

n = 20

Plug in the variable:

Angle EFG:

3(20) + 22

60 + 22

Angle EFG = 82 degrees

Angle GFH

4(20) + 18

80 + 18

Angle GFH = 98

Check:

98+ 82 = 180 degrees

180 degrees was the total so the answer is correct.

malfutka [58]

<u>Complete Question</u>

The usher at a wedding asked each of the 80 guests whether they were a friend of the bride or of the groom. The results are: 59 for Bride, 50 for Groom, 30 for both. Find the probability that a randomly selected person from this sample was a friend of the bride OR of the groom.

Answer:

0.9875

Step-by-step explanation:

Total Number of Guests, n(S)=80

Let the Event (a friend of the bride) =B

Let the Event (a friend of the groom) =G

n(B) =59

n(G)=50

n(B \cap G)=30

Therefore:

n(B \cup G)=n(B)+n(G)-n(B \cap G)\\n(B \cup G)=59+50-30\\n(B \cup G)=79

Number of Guests who was a friend of the bride OR of the groom = 79

Therefore:

The probability that a randomly selected person from this sample was a friend of the bride OR of the groom.

P(B \cup G) =\dfrac{n(B \cup G) }{n(S)} \\\\=\dfrac{79 }{80}\\\\=0.9875
