First we know that,

3x+15=5x-65 because of vertical angle thr.

y=y because of reflex property

there are 360 degrees in a circle so..

3x+15+5x-65+2y=360

3x+15=5x-65

x=40

so each 2 of the angles are...(40*3+15)=135

Then your new equation is

135+135+2y=360

2y=90

Hope this helps :)

Suppose △ITH≅△APG.<br><br> Which congruency statement is true?

kupik [55]

It is given that the triangles ITH and APG are congruent.

When the two triangles are congruent, then the corresponding angles and sides are congruent to each other.

By being congruent, the corresponding angles which are congruent are:

$IT \cong AP, TH \cong PG, IH \cong AG$

Therefore, $IH \cong AG$

SO, Option 2 is the correct answer.
