Sin 3θ = 0
3θ = sin^-1 0 = nπ
θ = nπ/3
5/3+3x+4= 8
= 3x= 4-5/3
= 3x= 7/3
= x= 7/9
Solution:
It is given that two triangles Δ ABC and Δ X Y Z are similar by Side -Side - Side(SSS) Similarity theorem.
So, the Statement which is given, that is →→∠B ≅ ∠Y and ∠B ≅ ∠Z, is inadequate for similarity criterion by SSS, as these statement are about angles of Triangles,not sides, which can't be true.
So, if the two triangles are Similar by SSS criterion , then the appropriate mathematical statement must be,
⇒
