Congruent means they are the same,
A and Q are both the first letters, which mean they would also be the same.
Set the two equations equal to each other, solve for x then solve for angle A.
x-10 = 2x-30
Add 30 to each side:
x+20 = 2x
Subtract 1x from each side:
x = 20
Now replace x with 20 in the equation for A
A = 20-10
Angle A = 10 degrees.
