Answer:
56°
Step-by-step 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 :)
