8x + 2x + 5x = 180
15x = 180
x = 180/12
x = 12
m∠1 = 8x = 8*12 = 96°
m∠2 = 2x = 2*12 = 24°
m∠3 = 5x = 5*12 = 60°
The product of 19 +85 is 104

Answer:
x = 12
Step-by-step explanation:
the two equations shown should add up to 180. so I did this equation: (10x-20)+ (6x+8) = 180 and I solved for x
5x/3=35
5x = 35*3=105
x= 105/5 = 21
double check 5 x 21 = 105
105/3 = 35
