Answer:
The answer to your question is:
2.-
a) ∠ACB + ∠ ACE = 7x + 54
b) ∠ACB = 115° ∠ ACE = 65°
3.-
a) They measure the same
b) ∠MFG = ∠EFN = 80°
Step-by-step explanation:
1.- ∠ACB and ∠ ACE are linear pairs so ∠ACB + ∠ ACE = 180
∠ACB = 5x + 25
∠ ACE = 2x + 29
∠ACB + ∠ ACE = 180 = 5x + 25 + 2x + 29
180 = 7x + 54
7x + 54 = 180
7x = 180 -54
7x = 126
x = 126 / 7
x = 18
Then ∠ACB = 5(18) + 25 = 115° ∠ ACE = 2(18) + 29 = 65
2.- ∠MFG ∠EFN are vertical angles
∠MFG = 7x - 18 ∠EFN = 5x + 10
They measure the same, then
7x - 18 = 5x + 10
7x - 5x = 18 + 10
2x = 28
x = 28/2
x = 14
∠MFG = 7(14) - 18 = 98 - 18 = 80 ∠EFN = 5(14) + 10 = 70 + 10 = 80
The correct answer is -308
Answer:
it is answer A
Step-by-step explanation:
answer A has the correct ordered pairs on the correct lines, and in the correct order, the others either have the lines, or the order, or the ordered pair in general mixed up.
Answer:
1/18
Step-by-step explanation:
First list all the 2 answers that may add up to 11:
5 and 6
6 and 5
There are no more.
Next how many possible outcomes can se get?:
6 x 6 = 36
Thus, the probability = 2/36 = 1/18
