You need the first term and the common ratio.
Lol I was looking for help for this question but I couldn't find it so I had to figure it out my self and the answer is 40
<span><span>Corresponding angles are congruent (same measure)So in the figure above, the angle P=P', Q=Q', and R=R'.</span><span>Corresponding sides are all in the same proportionAbove, PQ is twice the length of P'Q'. Therefore, the other pairs of sides are also in that proportion. PR is twice P'R' and RQ is twice R'Q'.
so the value of x :
x / 110 = 21.6 / 72
solve for x
x = 33</span></span>
