Question

i 1) Define supplymentry angles​

Answer 1

Answer:

either one of two angles which add up to 180o

Answer 2

Step by step explanation :-

Supplementary angles :-

The sum of two angles is 180° then the two angles are called Supplementary angles .Let the two angles are x, y Since ATQ to definition ∠x + ∠y = 180°

Lets look some examples !

130° , 50° are Supplementary angles Since sum of 130°and 50° is 180°

90° , 90° are Supplementary angles 90° + 90° = 180°

170° , 10° are Supplementary angles 170°+ 10° = 180°

Some Different Questions about Supplementary angles :-

1 ) Two angles are Supplementary If one of angle is 49° Then the other angle is ?

Solution :- Let the other angle be x

As we know sum of two angles is 180°. Since ,

49° + x = 180°

x = 180° - 49 °

x = 131 °

So, the other angle is 131 °

2 ) Two Supplementary angles are in ratio 1 : 3 Then find angles

Solution:- Let the two angles be 1x , 3x

Since, we know those two angles sum should be 180° So,

1x + 3x = 180°

4x = 180°

x = 180°/4

x = 45°

1x = 1(45) = 45°

3x = 3(45) = 135°

So, the two angles are 45°, 135°
