Question on: WAEC Mathematics - 1992
In the diagram above PQT is a tangent to the circle QRS at Q. Angle QTR = 48° and ∠QRT = 95°. Find ∠QRT
A
48o
B
45o
C
37o
D
32o
Ask EduPadi AI for a detailed answer
Correct Option: C
∠RQT = 180° - (95° + 48°) = 73°
∠OQR = 90° - 37° = 53°
∠QOR = 180° - (53° + 53°) = 74°
QSR = 74°/2 = 37°
