Answer:
x=19 and y=8 m<Q is 79
Explanation:
Since they have to be congruent triangles, all the corresponding parts are congruent so you would make the equation 2x+2=x+21 and you solve that for x. Then you would make the equation 8y-4=4y+28 and solve for y. You get the measure of angle Q by figuring out the measures of the other two angles and since you know that that the measures of all three triangles add up to 180, angle Q is 79 degrees.
