Answer:

1

Step-by-step explanation:

21 = 3*7

65 = 5*13

CGF: to find the greatest common factor, multiply those factors both numbers have in common

GCF :1  since there are no factors in common

Answer:  1 ✔


Step-by-step explanation:

The factors of 21 are: 1, 3, 7, 21

The factors of 65 are: 1, 5, 13, 65

Then the greatest common factor is 1.

They both contain a one in their factors so the GCF for both is 1.

What is the length of x in the diagram below?
luda_lava [24]

Answer:

That is a 45-45-90 triangle next to a 30-60-90 triangle.  

So, the height of the left triangle equals 5.

That makes the short side of the 30-60-90 triangle also equal to 5.

In a 30-60-90 triangle, the hypotenuse (or "x") is exactly twice the length of the shortest side.

Therefore, the hypotenuse (or "x") equals 10.
