A section of a rectangle is shaded to form a rhombus. The length of one side of the rectangle is 15, and the height is x. The shaded figure is a rhombus. The area of the shaded section is 60 square units.

To find the area of a trapezoid use the expression 1/2h (b1 + b2), where h represents the height b1 represents the length of the top base and b2 represents the length of the bottom base.

A business has a 200 ft wall and places 6 ft letters on the center of an exterior wall to spell SALE. If there is 1ft between each letter, where do they start the letter S?

Solve each equation 1. r - 38 = 9 2. h + 17 = 40 3. n + 75 = 155 4. q - 17 = 18

3 x [9 - (4+2) divided by 2]

First, we need to find the radius: r = sqrt ((-3) ^2 + 1^2) = sqrt (10) sin (theta) = y/r = 1/sqrt (10) = sqrt (10) / 10 cos (theta) = x/r = - 3/sqrt (10) = - 3sqrt (10) / 10 tan (theta) = y/x = - 1/3
