Answer:

The measured from a left-hand turn on the oak road must be 103 degrees

Explanation:

Let

x ----> measured in degrees from a left-hand turn on the oak road

y ----> measured in degrees from a right-hand turn on the oak road

we know that


m\angle x+m\angle y=180^o ----> by supplementary angles (form a linear pair)

we have


m\angle y=77^o ---> given problem

substitute


m\angle x+77^o=180^o

solve for
m\angle x


m\angle x=180^o-77^o\\m\angle x=103^o

therefore

The measured from a left-hand turn on the oak road must be 103 degrees
