10. the angles opposite the congruent sides of an isosceles triangle are congruent. find the value of x in the triangle. show all your work. /x\ / \ / 70 \ < triangle

Ok so the triangles angle need to add up to 180degrees, and we no that one side out of the 3 is 70 degrees. the other2 sides need to be the same cuz there congruent. first do 180-70=110degrees but that's not the answer because we have two side and we cant wright in 110 for both cuz 110+110+70 does not equal 180, so what you do is divide 110 by 2 110/2=55 so your answer 55 degrees for x (the 2 missing sides) hope this .

I can’t help because I can’t see the coordinate plane.
