8x° -9°

Answer 1

`\text{The two triangles shown here are congruent by S.S.S. axiom because the}\\\text{three corresponding sides of the triangles are equal.}\\\text{Congruent triangles have corresponding angles equal too. }\\\therefore\ 6x+15^o=8x-9^o\\\text{or, }8x-6x=15^o+9^o\\\text{or, }2x=24^o\\\text{or, }x=12^o`
