But the adjacent of a triangle can't have a negative measurement.
So:

Recall that:


Substitute 7 for b in the above expressions






Hence, the dimensions of the triangle are:



They are actually the same.....Hope this helped you!!
Answer:
9-3x=0
Step-by-step explanation:
Add 3x to both sides
9=3x
divide both sides by 3
3=x
x=3
You would multiply 6 by 3 and x by 4. You would end up getting 4x = 18 and then you simplify that to get 9/2 or 4.5.
