Answer:
23
Step-by-step explanation:
we are given that angle NRQ is 78 degrees
we can see from the figure that the sum of the given angles is angle NRQ
so
(8x + 7) + (4x - 1) = 78
12x + 6 = 78
12x = 72
x = 6
Now, we have to find angle PRQ
replacing x with 6 in the equation of angle PRQ
PRQ = 4(6) - 1
PRQ = 23
y=9%
x=18%
It is in a pattern like x=y+y
I know that the two means are are 11.28 and 12.
I could be wrong but I did the math 5 times.
9.28/2.9=3.2is a required answer
n=105 just multiply 3*35 youll get 105
