So n will be the unknown, and the expression is:
6n = 24
from where we can find the number n:
n = 24/6
n = 4
Answer:
The choice third ; a=9 , c= 18
Step-by-step explanation:


OM=18, so OQ=QM=18/2=9.
Given QU=8
from figure OQU is a right angled triangle , so OU^2=OQ^2 + QU^2
OU^2 = 9*9 + 8*8 = 81+72=153;
OU=sqrt(153) = 12.37 =13(approx);
From given statements of congruent NT and OU will also be congruent or identical. So, NT=OU=13
