Ijust started back up with school and they already gave us hw on the second day and i don’t understand it because she don’t go over anything and then just gave us hw these are the questions i need to show the
1) -5-2(-3) plus 2^3
2) 12 divided by 3 divide plus 1
3) -2(10-7) -4
4) 30-6 • -4 +-1^3
5) -2(20-2) -4^2
6) -2^3 +2(14-6)+-2
7) -3+ -2 • 2^3

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

y -5 = (-1/4)(x + 8)
