Find the greatest common divisor of 252 and 60

12

Step-by-step explanation:

The greatest common divisor(gcd) is also known by the name highest common factor(hcf), greatest common factor(gcf).

Greatest common factor of two number can be defined as the highest  integer that divides both the number.

We have to find greatest common divisor of 252 and 60.

The prime factorization of 252 is:

252 = 2×2×3×3×7

The prime factorization of 60 is:.

60 = 2×2×3×5

Common factors are: 2×2×3

Hence, greatest common divisor of 252 and 60 = 2×2×3 = 12

i do not know this sorry : (

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
