Asign company is building a sign with the dimensions shown.
10 ft
13 ft
what is the area, in square feet, of the sign?

 A = 130 ft²

Step-by-step explanation:

Since the dimensions are different, the sign is rectangular in shape.  The formula for area if a rectangle is A = LW, here we have

A = 10(13)

   A = 130 ft²

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

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
