Answer:
C.
Step-by-step explanation:
The eqn. of a circle with centre (h,k)and radius ris given by,
Since both trapezoids are similar, so LMNO is a scaled version of QRST by some magnitude
so we can easily use the concept of ratios to find x
in other words: x÷2=6÷5
so x=6×2÷5=12/5=2.4
x=2.4
Answer:
