Answer:

46

Step-by-step explanation:

180-70=110

now we can take a guess on the other two. What two numbers added up make 110 and are 18 apart? 46 and 64 have 4 and 6. That makes 10. So now I know that the first and second angles are 46 and 64. According to the question, the first angle is smaller. So the first angle is 46.

Answer:

first angle = 46 and the second angle = 64

Step-by-step explanation:

(x,x-18,70)

x+x-18+70=180

2x+52=180

2x=180-52

2x=128

x=64

(x+x-18+70) since x is 64 replace;

x=64

x-18= 64-18= 46
