There exists a similar question where m angle 2 is 9y + 4. If the angles are supplementary, the sum of their measures is 180 degrees. The equation that represents this situation is,
4y + 7 + 9y + 4 = 180
The value of y is equal to 13. The value of the measure of angle 2 is equal to 121 degrees.

b) May normality of p be assumed?
Condition for normality : np>10 and np(1-p)>10.
and
27.871 and 26.561063
Hence p is assumed to be normal since the condition is satisfied
