choose all answers that apply:

(choice a)
a
5, 6, 75,6,75, comma, 6, comma, 7

(choice b)
b
6, 8, 106,8,106, comma, 8, comma, 10

(choice c)
c
9, 9, 189,9,18

B {6, 8, 10}

Step-by-step explanation:

The lengths of choice C do not even form a triangle.

The lengths of choices A and B are both arithmetic sequences. The only arithmetic sequence of side lengths that forms a right triangle is a multiple of 3, 4, 5. Choice B is that sequence multiplie by 2.

The lengths of choice B will form a right triangle.

its definatley   this on your answer choice?

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
