A company makes 110 bags. 46 of the bags have buttons but no zips.
20 of the bags have zips but no buttons.
39 of the bags have neither zips nor buttons.
How many bags have zips on them?

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

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

step-by-step explanation:

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4
