The 2 marked angles are alternate angles and so they are equal.
Therefore:- 3x + 5 = 65
3x = 60
x = 20 (answer)
2 + 4 (c + 7)
2 + 4c + 28
combine liked terms
4c + 30
Answer:
B) 30 + 4c
F + V = E + 2
F = 25
V = 17
25 + 17 = E + 2
42 = E + 2
42 - 2 = E
40 = E <== there are 40 edges
You simplify a fraction by finding it's greatest common factor. A greatest common factor is what both numbers are divisible by. If they can both be divided by two, then you've simplified them a little bit. Keep going until you can't find a common number that can be divided by the two, and you've got your simplified fraction. For example, 10/5 = 1/2 since both 10 and 5 is divisible by 5.
