Hey there!
The base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent. The Isosceles Triangle Theorem states that the perpendicular bisector of the base of an isosceles triangle is also the angle bisector of the vertex angle.
Let me know if you are still confused and need a better explination :)
Have a great day!

To solve for
, we need to isolate it on one side of the equation.
The most important part of this is knowing that whatever we do to one side of the equation, we must also do to the other.
Subtract 32 from both sides of the equation.

Divide both sides of the equation by
.

Yes 90 is 1/10 of hundred
If There is a math equation you can use math-way.
Also it would help if you can take a better picture.
Once you take a better picture I promise i will try my best to answer the question.
For example you can take the number 7 7 7 7
(7)77{7}
The first seven is the greatest it's 7,000
The last seven is the least its 7
HOPE THIS HELPS!!!
