Answer:
3
Step-by-step explanation:
We factor each of these (find prime factorization ) and the largest factor is 3
GCF = 3
The factors of 6 are: 1, 2, 3, 6
The factors of 27 are: 1, 3, 9, 27
The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30
Then the greatest common factor is 3.
42°
The interior angles of a triangle always add to 180 degrees.
90+48+x=180
x=180-90-48
=42
x is 42°
Answer:A=62AED B=93 C=155
You add all of the numbers to split between (2,3,5) you get 10
then you divided 310 by 10 which is 31
then you times 2 by 31=62 (a)
3x31=93 (b)
5x31=155 (c)
7x - 3 = 6x + 17
7x - 6x = 17 + 3
x = 20
Solution → x = 20°
