Answer 1

Answer:

Q7) LET THE THREE INTEGER BE X,X+1,X+2

= X+X+1+X+2 = 5+X

= 3X+3=5+X

= 3X-X = 5-3

= 2X = 2

X = 1

Q8) PERIMETER OF TRIANGLE = SUM OF ALL SIDES

= 30 = 9+9+X

= 30 = 18+X

= 30-18 = X

= 12 = X

Q9) LET ONE ANGLE BE X

SECOND ANGLE X + 10

THIRD ANGLE= X+20

SUM OF ANGLES IS 180 DEGREE

X + X +10+X+20=180

3X+30=180

3X= 150

X = 150/3

X = 50 DEGREE

SECOND ANGLE = 60 DEGREE

THIRD ANGLE = 70 DEGREE
