Question

Geometry heeelp i need help asap i will give 100 points and brainiest.

Answer 1

Answer:

x = 2

Step-by-step explanation:

This triangle isosceles because of it's two marked congruent sides.

Using base angle theorem, reflexive property (the line in the middle is congruent to itself), and given, we can prove that the two triangles are congruent.

Now that we have proved triangle congruency (SAS), we know that:

17x-3 = 9x+13

Plus 3 on both sides and minus 9x on both sides

8x = 16

Divide by 8 on both sides to isolate x

x = 2

Hope this helps :)

Have a nice day!

Answer 2

Answer:

X=2

Step-by-step explanation:

You can prove the triangle congruent by SAS. First, reflexive property and then isosceles triangle theorem since two side is congruent, the opposite angle is congruent to each other because of that theorem and then cpctc
