Can someone help with number 1? i’ll give brainliest ;)

Sally must get 95% in her sixth test!

Step-by-step explanation:

To get an average of 93 over 6 tests, the total must be

6*93 = 558

Therefore the sixth test she must get

S = 6*93 - 87 -96 -98 -90 -92 = 95

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

what i would say the best answer is a. 40.5
