Question

find the suplimentry angel of the given angle. (I) 105​

Answer 1

Supplementary angles add up to 180°

hence,

one angle = 105

other angle = 180 - 105

Supplementary angle = 75°

Hope it helps

have a great day

Answer 2

suplimentary means sum of angles is 180°

given angle is 105 and let another angle be x

so x+105 = 180°

x = 180-105

x =75°

there fore, another suplimentary angle be 75°
