2 GEOMETRY QUESTIONS

1. A. 2. Not all even numbers are perfect squares. In fact, many perfect squares are odd numbers. The first ten perfect squares are 1, 4, 9, 16, 25, 36, 49,...

Step-by-step explanation:

The first answer is D. Im not sure about the second question and when its says list a counterexample.

Step-by-step explanation:

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

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
