Answer:
48.
Step-by-step explanation:
1). <C = 74 because it forms a supplemetary angle 180- 106 = 74.
2). We know that the sum of all the angles in a triangle is 180 so we need to add them.
3). 4y + 3y +22 + 74= 180
4). simplify 7y +96=180
5). isolate y so we must subtract 96 from either side.
6). 7y= 84 now divide by 7 on each side. 84/7 = 12.
7). Now we know y = 12 and that angle A is equal to 4y.
8). <A = 4(12) now distrubute
9). <A= 48 degrees
GOD, BLESS!!!
