The lengths of the three sides of a triangle are 10, 14, and 18 inches. Determine whether this triangle is a right triangle.
The measure of an angle is 8 less than three times its complement. Find the measure of the angle.
The length of a side of a square is 5x+2 units. If it has a perimeter of 48, what is equation for the perimeter? What is the value of x? What is the area of the square?
The perimeter of a rectangle if 68 feet. If the length is 8 feet more than the width, find both the length and width. (Formula: P = 2L + 2W)
A rectangle has a length of 12 and a width of 2x. If the area of the rectangle is 12, what is the rectangle's perimeter?
A garden has the shape of a right triangle with one leg 9 meters longer than the other. The hypotenuse is 9 meters less than twice the length of the shorter leg. What is the length of the shorter leg?
A triangle has one interior angle that has a measure 45°, another interior angle that has measure x°, and an exterior angle that has measure 85°, as shown in the diagram. What is the value of x? In a certain triangle, the longest side is 1 foot longer than the second longest side, and the secondlongest side is 1 foot longer than the shortest side. If the perimeter is 21 feet, how many feet long is the shortest side?
