Icreated a graph and did as told but i need with these other follow-up questions!

4) find the length of all 4 sides of your trapezoid(show all work.

5) describe two different triangle congruence postulates and how to use 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

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

m∠a is 90°

m∠b is 40°
