Which is a true statement about the diagram? m?5 + m?6 = m?1 m?3 + m?4 + m?5 = 180° m?1 + m?2 = 180° m?2 + m?3 = m?5

If m?X = 34° and m?Z = 26°, what is m?Y? m?Y = 26° m?Y = 34° m?Y = 60° m?Y = 120°

What is the value of h? h = 20 h = 35 h = 55 h = 70

What is the value of k? k = 28 k = 29 k = 31 k = 42

Which statement regarding the interior and exterior angles of a triangle is always true? An exterior angle is supplementary to the adjacent interior angle. An adjacent interior angle is supplementary to a remote interior angle. A remote interior angle is congruent to the exterior angle. An exterior angle is supplementary to a remote interior angle.

Which angle has a measure equal to the sum of m?SQR and m?QRS? ?RSC ?SRE ?DQS ?QSR

Which statement regarding the diagram is true? m?WXY = m?YXZ m?WXY < m?YZX m?WXY + m?YXZ = 180° m?WXY + m?XYZ = 180°

What is the value of x? [Art not to scale.] x = 23 x = 35 x = 58 x = 93

Find the value of x. x = 2 x = 3 x = 33 x = 52
