Find the greatest number by which 90, 120 and 150 are exactly divisible.​

answer=30

among all the divisions of these numbers 30 is the largest. So it is the answer

okey that's a good question

Step-by-step explanation:

90 120 150 |2•

45 60 75 |3•

15 20 25 |5•

3 4 5 |3

1 4 5 |4

1 1 5 |5

1 1 1

if we want to find which number is greatest number to divide we must multiply by 2, 3 and 5 because they are common number to divide

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

a
