How did you arrive to that answer?

Remember that if EB is perpendicular to BC, then angle EBC is 90 degrees.

subtract 3y
PhantomCrow
  • PhantomCrow
From what?
meilendurcer
  • meilendurcer
7y
PhantomCrow
  • PhantomCrow
Hm. It says that angle EBF is 7y-3 and angle FBC is 3y +3.
meilendurcer
  • meilendurcer
\[7y-3=3y+3\]
PhantomCrow
  • PhantomCrow
These two angles make up angle EBC
PhantomCrow
  • PhantomCrow
It isn't given that the two angles are congruent. If the value of the two angles were congruent, then this would work. But that info isnt given

  • meilendurcer
i know there's another way to put them but i forgot my notes
PhantomCrow
  • PhantomCrow
Its fine. You see that EBF AND FBC equal EBC, right?
meilendurcer
  • meilendurcer
yes
PhantomCrow
  • PhantomCrow
Alright. And since the question tells us that assuming EBC is perpendicular, what is the value of y. So EBC=90. \[(7y-3)+(3y+3)=90\]
meilendurcer
  • meilendurcer
yeah that's the one
PhantomCrow
  • PhantomCrow
Alright. So now use algebra to solve for y and see what you get.
meilendurcer
  • meilendurcer
y=9?
PhantomCrow
  • PhantomCrow
Yep.
