What
is a common factor of 72 and 108

the step by step explanation gives you your answer

Step-by-step explanation:

The first step to find the gcf of 72 and 108 is to list the factors of each number. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72. The factors of 108 are 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54 and 108.

the greatest common factor (GCF)for 72 and 108 ,notation CGF(72,108),is 36.

Step-by-step explanation:

the factor of 72 are 1,2,3,4,6,8,9,12,18,24,36,72;the factors of 108 are 1,2,3,4,6,8,9,12,18,27,36,54,108.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
