If angle 1 and angle 2 form linear pair and m angle 1 =50, then m angle = 2

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
