Answer:
Step-by-step explanation:
a). Ratio of OP and RT = 
= 
= 
b). Since ΔOPQ ~ ΔRTS, their corresponding sides will be proportional.


OQ = 
OQ = 15 cm
c). m∠P = m∠T = 60°
d). m∠Q = m∠S
By applying angle sum theorem in ΔRST,
m∠R + m∠S + m∠T = 180°
26° + m∠S + 60° = 180°
m∠S = 180° - 86°
= 94°
Therefore, m∠Q = m∠S = 94°
The decrease:
125000 - 117500 = 7500
Percentage of decrease = 7500/125000 x 100 = 6%
