First do distributive property
2x + 10 + 3x = 30
Now combine like terms

Identify which triangles are congruent, and explain your answer.

Paha777 [63]

I believe that A and D would be the correct answer. Because both are 30,60,90 triangles and would be congruent. The other 2 triangles only have 1 angle and their side measures are at two different places meaning they cannot be congruent.
