Yogita Ingle 6 years, 3 months ago

11x+15y+23=0
11x+15y= -23. (equ.1st)

7x-2y-20=0
7x-2y=20. (equ.2nd)

11x+15y=-23
7x-2y = 20

multiply by (2) in equ. 1st &( 15) in equ. 2nd we get.

22x+30y= -46. ( equ. 3rd)
105x-30y= 300. (equ. 4th)
_____________
127x=254

X=254/127
X = 2.

put the value of X in equ. 2nd

7x-2y=20
7(2)-2y =20. (X=2)
14-2y =20
-2y=20-14
-2y= 6
y= 6/-2
y=-3.

Your answer => X = 2 , Y= -3.

Sin(45+A)-cos(45-A) =sin(90-(45+A))-cos(45-A) =cos(45-A)-cos(45-A) =0

1Thank You

Yogita Ingle 6 years, 3 months ago

sin(45° + A) - cos(45° - A)

= sin(45° + A) - sin[90° - (45° - A)]

= sin(45° + A) - sin(90° - 45° + A)

= sin(45° + A) - sin(45° + A)

= 0.
