Answer:

123

Step-by-step explanation:

supplementary angles add up to 180

(5x - 22) + (x + 28) = 180

5x - 22 + x + 28 = 180

6x + 6 = 180

6x = 180 - 6

6x = 174

x = 174/6

x = 29

<A = 5x - 22 = 5(29) - 22 = 123

Supplementary angles add up to 180

∠A+ ∠B=180
put the values
5x-22+x+28=180
6x+6=180
6x=180-6
6x=174
x=174/6
x=29

put the value of x in ∠A
5x-22
5(29)-22
145-22
123

Therefore ∠A is 123
