Answer:
Explanation:
a). Ratio of OP and RT =
![(OP)/(RT)](https://img.qammunity.org/2022/formulas/mathematics/high-school/bnyv6iqf5gc96376scszfckivkwu906lhj.png)
=
![(12)/(3.6)](https://img.qammunity.org/2022/formulas/mathematics/high-school/8zeqlv8c0ibnutkptt20ll854zeojahhco.png)
=
![(10)/(3)](https://img.qammunity.org/2022/formulas/mathematics/high-school/78oxyy8jh8dh6z3nvv55nlk1sm1zjg1xa6.png)
b). Since ΔOPQ ~ ΔRTS, their corresponding sides will be proportional.
![(OQ)/(RS)=(OP)/(RT)](https://img.qammunity.org/2022/formulas/mathematics/high-school/3qdz0z6yk4zrenk3469hqwbwncf3xa4554.png)
![(OQ)/(4.5)=(10)/(3)](https://img.qammunity.org/2022/formulas/mathematics/high-school/ofivwk1agb1f2ekp64qbxiu1q5ag33wsge.png)
OQ =
![(10* 4.5)/(3)](https://img.qammunity.org/2022/formulas/mathematics/high-school/8qyntbo9riae71nqrvxt0zh59k7hh33moz.png)
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°
