• Solving equations related to geometry

If the perimeter of a rectangle is 90 cm, and the short side is x, what is the expression for the long side?

• x + 2

• x + 8

• x + 4

• x + 6

How do you calculate the perimeter of a rectangle?

• Multiply the length by the width

• Multiply all sides together

• Add the length and width, then multiply by 2

• Add all the sides together

What is the sum of the angles in a quadrilateral?

• 360 degrees

• 270 degrees

• 450 degrees

• 180 degrees

If one angle in a quadrilateral is 90 degrees, and another is 65 degrees, what is the expression for the remaining angles if they are 2x and x + 10?

• 2x + x + 10 = 180

• 2x + x + 10 = 270

• 2x + x + 10 = 360

• 2x + x + 10 = 205

What is the sum of the angles in a pentagon?

• 360 degrees

• 540 degrees

• 900 degrees

• 720 degrees

In a pentagon, if one angle is 150 degrees and another is 3x - 30, what is the expression for the sum of the angles?

• 3x - 30 + 150 = 720

• 3x - 30 + 150 = 180

• 3x - 30 + 150 = 360

• 3x - 30 + 150 = 540

If x equals 50 degrees in a pentagon, what is the measure of an angle represented by 2x?

• 100 degrees

• 200 degrees

• 50 degrees

• 150 degrees

What is the measure of an angle represented by 3x - 30 if x equals 50 degrees?

• 90 degrees

• 150 degrees

• 180 degrees

• 120 degrees

If the angles in a pentagon are 100, 120, 100, 120, and 100 degrees, what is their sum?

• 900 degrees

• 720 degrees

• 540 degrees

• 360 degrees
