which of the following is an irrational number?
a) square root 25
b) square root 36
c) square root 50
d) square root 64

C

Step-by-step explanation:

An irrational number cannot be expressed in the form

where a and b are integers

A

= ± 5 ← both integers

B

= ± 6 ← both integers

C

= 5 ← is irrational

D

= ± 8 ← both integers

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
