Step-by-step explanation:
Answer: B. Similar - AA
Step-by-step explanation:
The AA or Angle-Angle postulate states that if two corresponding angles are congruent, then the triangles are congruent.
Take the first bracket and it's multiplication, 3(2a+5)
You expand my multiplying everything inside the bracket by the number outside.
3*2a = 6a
3*5 = 15
Then multiply out the second bracket, 5(a-2)
5*a = 5a
5*-2 = -10
So now you have 6a + 15 + 5a - 10
Simplify it by collecting like terms, and you have:
11a + 5
And that's the answer, hope I helped!
