Find angle PTQ angle QTU angle SUT angle RUQ angle RQU angle UQT
Answers
Step-by-step explanation:
In triangle PTQ,
angle PTQ + angle TPQ + angle TQP = 180° (Angle sum property of a triangle)
angle PTQ + 90° + 20° = 180°
angle PTQ + 110° = 180°
angle PTQ = 70°
angle PTQ + angle QTU + angle UTS = 180° (Straight angle)
70° + angle QTU + 45° = 180°
angle QTU + 115° = 180°
angle QTU = 65°
In triangle TSU,
angle STU + angle TSU + angle SUT = 180° (Angle sum property of a triangle)
45° + 90° + angle SUT = 180°
135° + angle SUT = 180°
angle SUT = 45°
In triangle TUQ,
angle TUQ + angle UTQ + angle TQU = 180° (Angle sum property of a triangle)
70° + 65° + angle TQU = 180°
135° + angle TQU = 180°
angle TQU = 45°
angle RQP = angle PQT + angle TQU + angle UQR
90° = 20° + 45° + angle UQR
90° = 65° + angle UQR
angle UQR = 25°
In triangle URQ,
angle URQ + angle RQU + angle QUR = 180° (Angle sum property of a triangle)
90° + 25° + angle QUR = 180°
115° + angle QUR = 180°
angle QUR = 65°
