5 Questions
1 Perimeter
A garden perimeter is \(26\text{ ft}\) with length \(8\text{ ft}\). Find the width \(w\):
\(2w + 16 = 26\)
A \(w = 5\text{ ft}\)
B \(w = 10\text{ ft}\)
C \(w = 13\text{ ft}\)
D \(w = 21\text{ ft}\)
2 Right Angle
Two angles make a \(90^\circ\) right angle. Solve for \(x\):
\(2x + 34 = 90\)
A \(x = 24^\circ\)
B \(x = 28^\circ\)
C \(x = 56^\circ\)
D \(x = 62^\circ\)
3 Triangle
A triangle has two equal sides \(s\) and perimeter \(20\text{ cm}\). Find \(s\):
\(2s + 6 = 20\)
A \(s = 4\text{ cm}\)
B \(s = 7\text{ cm}\)
C \(s = 14\text{ cm}\)
D \(s = 26\text{ cm}\)
4 Line Segment
A total line segment has length \(35\text{ in}\). Solve for \(x\):
\(3x + 5 = 35\)
A \(x = 6\)
B \(x = 10\)
C \(x = 15\)
D \(x = 30\)
5 Supplementary Angles (Straight Line = \(180^\circ\))
Straight Line
Two angles on a straight line add up to \(180^\circ\). Solve for \(x\):
\(4x + 60 = 180\)
A \(x = 15^\circ\)
B \(x = 30^\circ\)
C \(x = 45^\circ\)
D \(x = 60^\circ\)
