Answer:

56°

Explanation:

hii!

to solve this, we need to know that the angles of a triangle all add up to 180 degrees.

we are going to make an x equation here.

2x+3x+40=180

5x+40=180

-40 -40

5x=140

/5 /5

x=28

angle a is 2x, so the answer would be 28*2 which is 56°

hope this helped out :)
