Find the unknown sizes of angles with step by step explanation please:

Step-by-step explanation:

y= 80 because alternate angles are equal

80+57=137

180-137= 43 because angles in a triangle add up to equal to 180

z= 43

180-80= 100

the angle P is 90 so 100+80+90=270

360-270=90 as the sum of the angles in a quadrilateral its 360

so

x= 90

y= 80

z= 43

hope that helped! :)

I would really appreciate it if i got a brainliest, its alr if u cant

90

80                            ^

43                              |

guy above is correct |

it would be:

c.parallelogram.
