Which statement below best applies to the following expression? 4√2-5√3
A.
the two terms cannot be combined because the radicands are not identical, and cannot be simplified so that they are identical
B.
the two terms cannot be combined because the indices are not identical
C.
the two terms cannot be combined because the resulting value of the subtraction would be negative

D.
the two terms may be combined

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

step-by-step explanation:

there are infinitely many solutions.
