Answer:

56°

Step-by-step explanation:

180 = 40 + (2x) + (3x)

180 - 40 = 40 + 5x - 40

140/5 = 5x/5

x = 28

2(28)

= 56

Answer:

m∠A = 56°

Step-by-step explanation:

A triangle contains 180°. So

180 - 40 = 140

2x + 3x = 140

5x = 140

x = 28

Now, plug in the value for x.

2(28) = 56

Check your work.

40 + 56 + 84 = 180
