write four solutions for the equation ax-by=2ab ................. guyzzz exam tomorrow..............pls reply ASAP..... !!!!!!!!!!!!!!!!
One of the factors of (9x2 -1)-(1+3x)2 is
(a)3+x (b)3-x (c)3x-1 (d)3x+1
- TAKE A PIECE OF PLYWOOD HAVING DIMENSIONS 30 cm multiply 30 cm.
- DRAW A LINE SEGMENT AB OF LENGTH ONE UNIT BY TAKING 2cm = 1 UNIT.
- CONSTRUCT A PERPENDICULAR BX AT THE LINE SEGMENT AB USING COMPASSES ( OR SET SQUARES ).
- FROM BX, CUT-OFF BC = 1 UNIT AND JOIN AC.
- USING RED COLOURED THREAD ( OF LENGHT EQUAL TO AC ) AND ADHESIVE, FIX THIS THREAD ALONG AC.
- WITH AC AS BASE AND USING COMPASSES ( OR SET SQUARES ), DRAW CY PERPENDICULAR TO AC.
- FROM CY, CUT-OFF CD = 1 UNIT AND JOIN AD.
- FIX GREEN COLOURED THREAD ( OF LENGTH EQUAL TO AD) ALONG AD WITH ADHESIVE.
- WITH AD AS BASE AND USING COMPASSES ( OR SET SQUARES ), DRAW DZ PERPENDICULAR TO AD.
- FROM DZ, CUT-OFF DE = 1 UNIT AND JOIN AE.
- FIX BLUE COLOURED THREAD ( OF LENGTH EQUAL TO AE ) WITH ADHESIVE
NOW REPEAT THE ABOVE PROCESS FOR A SUFFICIENT NUMBER OF TIMES. THIS IS CALLED "A SQUARE ROOT SPIRAL"OBSERVATION
ON ACTUAL MEASUREMENT, WE HAVE
AC = _________________, AD = ________________,AE = _______________,AF = ______________________,
AG = ___________________,
ROOT 2 = AC = ___________________________ ( APPROX )
ROOT 3 = AD = ________________________
ROOT 4 = AE = __________________
ROOT 5 = AF = __________________
____________________________
____________________________
ans-
let the first angle be x
second angle be x-90 degree
therefore , x+(x+25)=90 degree
2x+25=90 degree
2x=90-25
2x=65
x=65/2=32.5
