Find the measure of angle A.

∠A = 65°

Step-by-step explanation:

All angles in a triangle add up to 180°.

Firstly, you need to solve for x.

Set all angles equal to 180°:

2x - 9 + 2x + 4 + x = 180

Combine like terms:

5x - 5 = 180

Add 5 to both sides:

5x = 185

Divide both sides by 5:

x = 37

Now, plug x into angle A:

∠A = 2(37) - 9

∠A = 74 - 9

∠A = 65°

Hope this helps!
