Answer:
B. 70
Step-by-step explanation:
<h3><u>look at the smaller triangle</u></h3>
its dimensions are : 
45 , 35 , 24
<h3><u>look at the bigger triangle ( this includes the dimensions of the smaller one)</u></h3>
its dimensions are :
45 + 45 ,  x , 24 + 24
= 90 , x  , 48
from the dimensions given we can notice that :
<em>bigger triangle dimensions are  = 2 * smaller triangle dimensions</em>
<em></em>
therefore to find the value of x :
x = 35 * 2
<h3><u>x = 70</u></h3>
<u />
<h3><u>hence the answer is B ) 70 </u></h3>
