Question

Q.1 Fill in the blanks
1)53+ (-37) =(-37)+ ........
2)Reciprocal of 8⅖ is .......
3) the supplementary angle of 123 is.........
​

Answer 1

Answer:

1.53

2.5/42

3.57°

Step-by-step explanation:

1.Commutative property

a+b=b+a

53+(-37)=(-37)+53

2.8⅖=42/5

Reciprocal = 5/42

3.Supplementary angles = Sum is 180°

So, 123+other angle= 180°

Other angle=180°-123°

Other angle= 57°
