Abriefcase measured 10 inch by 4.8 inch by 13.7 inch . find the volume of the briefcase

657.6 in ^3

Since the briefcase is in the shape of a cuboid... The volume of a cuboid which is Length x breadth x height can be used.

10 x 4.8 x 13.7 = 657.6 inch^3

step-by-step explanation:

because of the levels

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
