Answer:

hope my answer helps you..........

Answer 2

Answer:

<ABF+<ABC=180

<ABC=180-138

<ABC=42

<ADC+<ADE=180

<ADE=180-80

<ADE=100

<ADE+<DAE+y=180

100+

<ACD=<ADC(is. triangle.)

then

<ADC+<ACD+x=180

80+80+x=180

160+x=180

x=180 - 160

x=20

<ACD+W=180

W=180-80

W=100

<ABC+W+Z=180

42+100+Z=180

Z=180-142

Z=38
