Correct Answer: Option B
Explanation:
< OUT = < OTU
< OUT = \(\frac{180^o - 70^o}{2} = \frac{110^o}{2} = 55^o\)
< RUT = 180o - 100o = 80o
< RUO = < RUT - < OUT
= 80o - 55o
= 25o
< OUT = < OTU
< OUT = \(\frac{180^o - 70^o}{2} = \frac{110^o}{2} = 55^o\)
< RUT = 180o - 100o = 80o
< RUO = < RUT - < OUT
= 80o - 55o
= 25o
