Step-by-step explanation:
60 degrees because vertical angles are congruent if you move line y 5 degrees clockwise then you are adding 5+55=60 and since 1 and 3are congruent 3=60 degrees
The margin of error is 0.97849
we are given
mean=235
so,

standard deviation =7.5
so,

we know that
ME=2*standard error
and

If confidence level is 95%, then we can multiply by 1.96
so, we can multiply by 2 to get ME
now, we can use marginal error formula

now, we can plug values
and we get
