What is the correct order of steps to solve this similarity problem?
If △DEF ~ △HJG; find x
x=20
Cross multiply to make the equation:
JG is the side that has to be in the proportion created because it contains x, so create a proportion using corresponding sides from each triangle:
Rewrite the similarity statement so that you can line up the corresponding letters from each polygon:
Simplify the equation to
Divide both sides of the equation by 9:
Replace the all the sides with numbers:
USE THE SIMILARITY RELATIONSHIP TO FIND THE INDICATED VALUE:
If △DEF ~ △HJG; find x
What is the correct order of steps to solve this similarity problem?
If △QRS ~ △TUV; find x
Divide both side of the equation by 54:
x=11
Rewrite the similarity statement so that you can line up the corresponding letters from each polygon:
Simplify the equation to
Replace the all the sides with numbers:
UT is the side that has to be in the proportion created because it contains x, so create a proportion with UT using corresponding sides from each triangle:
Cross multiply to make the equation:
Subtract 270 from both sides of the equation:
