You are designing a room for a house and are drawing a floor plan. the room is actually 18 feet wide. on your floor plan, you draw the room as 6 feet wide. what is the scale factor for the floor plan?

answer: the actual length and width of a room is 18 feet by 12 feet. the length and width of scale drawing of the room is 12 inches by 8 inches. what is the drawing?

step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

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
