Question

1.] divide the polynomial by given monomial = 9x+3xsqaure+underroot 3 by underoot 3
2.] three no. are in the ratio 3:4:5 if the sum of the largest and the smallest equal to the sum of the third and 52. find the no.
3.] abcd is a rectangle with angle bac = 32 degree. determine angle dbc.
4.] two adjacent angles of a parellelogram are in the ratio 3:8 and its perimetre is 110 cm. find the sides of a parallelogram.

Answer 1

1.). 9x+3x^2 +√3÷√3
=√3(3√3x+√3x^2+1)÷√3
=3√3+√3x^2+1
2.)let no.1 be 3x
no.2 be 4x
no.3 be 5x
given 3x+4x=5x=52
7x-5x=52
2x=52
x=26
3.)as rect. is a parallelogram
so, the diagnols bisect each other
so, OA =OB
ang. oab = ang. oba (ang. opp. to equal sides are equal)
now,oba =32°
ang. abc=dba+dbc
90°=32°+dbc
dbc=58°
4.) There may be side in the place of angle then the answer will come..
If other answers are correct mark as brainliest answer...
