Answer 1

a- 47+x=180

x+y=180

47+x=x+y

y=47°

72°+z=180

z=108°

x=133°

$\boxed{ \boxed{ \boxed{ \mathsf{x = {133}^{o} \: e \: y = {47}^{o} \: e \: z = {108}^{o} }}}}$

_______________

b- 3z+1+110=180

3z=69

z=23°

y+62=3y

62=2y

y=31°

x/3+3×31=180

x/3=87

x=261°

$\boxed{ \boxed{ \boxed{ \mathsf{x = {261}^{o} \: e \: y = {31}^{o} \: e \: z = {23}^{o} }}}}$
