What is the sum and classification of Two-fifths + StartRoot 88 EndRoot?

“A. 9.78083151..., irrational.

Step-by-step explanation:

We are asked to find the sum and classification of \frac{2}{5}+\sqrt{88}

5

2

+

88

.

Since 88 is not a perfect square, so we will find the value of square root of 88 using a calculator.

\frac{2}{5}+9.3808315196468591

5

2

+9.3808315196468591

Upon adding both numbers we will get,

9.78083151964685919.7808315196468591

Since 2/5 is a rational number and \sqrt{88}

88

is an irrational number as its decimal values are not terminating, therefore, the sum of both numbers will result in an irrational numbers”

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
