Step-by-step explanation:

7x +5x = 180

12x = 180

x = 180 /12

x= 15

7x = 15 * 7

= 105:

5x = 15 * 5

= 75

Answer 2

LET THE ANGLES BE 7x AND 5x

Now, ATQ

7x + 5x = 180°

12x = 180°

x = 180

12

x = 15

1st ANGLE = 7x = 7 X 15 = 105°

2nd ANGLE = 5x = 5 X 15 = 75°

the two supplementary angles are 105° and 75°
