(I ALSO NEED THE FILL IN THE BLANKS)

CHAPTER lines and angles class 7
( I NEED the blanks if you don't know the fill in the blanks don't answer it) ​

Answer 1

Step-by-step explanation:

the sum of two adjacent angles is 180 degree

so,

3x-40+x=180

4x=180+40

x=220/4

x=55

therefore 3x-40= 165-40=125

so the answers of the boxes are

1.55

2.55

3.125
