Question

find the supplementry of each of the following angle. 1) 105° 2)57° 3)130°​

Answer 1

Step-by-step explanation:

supplementary angles make 180

let the unknown angle in each case be x, y, z respectively

1) 105 + x = 180

x = 180 - 105

x = 75

2) 57 + y = 180

y = 180 - 57

y = 123

3) 130 + z = 180

z = 180 - 130

z = 50

Answer 2

Answer:

1) 75°

2) 123°

3) 50°
