Answer:
x = 31 and y= 11
Explanation:
Since sum f angles on a straight line is 180°, hence;
2x+8+3x+17 = 180
Collect like terms
5x+25 = 180
5x = 180-25
5x = 155
x = 155/5
x = 31°
Similarly;
3x+17+5y+15 = 180
Substitute x = 31 into the equation
3(31)+17+15+5y = 180
93+32+5y = 180
125+5y =180
5y = 180-125
5y = 55
y = 55/5
y = 11°
Hence x = 31 and y= 11
