The answer should be d. 261
Because of the distance formula you should get this
The answer is C 43-(16+11)
A shows 11 plus the sum of 43 minus 16
B shows the sum of 16 plus 11 minus 43
Answer:
if A is proportional to B
then A = B
what they are saying is that triangle 1 = triangle 2
so the values are the same just put whatever value is shown on triangle A unto triangle B
hence,
X=15
