80
34-1 plz solve the second one​

Answer 1

Step-by-step explanation:

interior <c =180-80 (l. p)

therefore, <c=100

now,

<d + <c =180 (adj. <s)

<d+100=180

<d=180-100=80

therefore, <d=80

So

In DAB and DCB

<d=<b=30 (inte. <s)

also, in DCB & DAB

<d=90-30=50

therefore <d=<b=50

so

<z=50

<y=30
