the points (0,8/3), (1,3) and (82,30) are vertices  of which type of triangle ( acute ,obtuse,right, isoseles etc)

7 years ago


Answers : (1)


the simplest way to determine the nature of the triangle is to compute the sides of it

 square of one side ,a^2 = { (0-1)^2 + (8/3 -3)^2  } = 10/9 =1.11

   b^2 = { (82-1)^2 + (30 -3)^2  } = 7290

 c^2 =  { (82-0)^2 + (30 -8/3)^2  } =7471.11

 it shows that , c^2 > a^2 + b^2

so the tiangle would be acute

Tangents PA and PB are drawn to a circle x2+y2=a2 from the point (×1,y1). Equation of circumcircle of triangle PAB is
Since the circumcircle of ∆ PAB, will have the diameter joining P and the centre of the circle x^2+y^2=a^2.i.e.( 0,0)Therefore , the eq. Of the circumcircle is [ x( x-x1) + y(y-y1). ]

If 2a+b+2c=0, then the family of lines ax+by+c=0 is concurrent at
Make ax+by+c=0 similar to 2a + b + 2c = 0 therfore multiply ax+by+c=0 by 2 .i.e. 2ax + 2by + 2c = 0 Now compare it with the coeff. of 2a+b+2c=0 we get, x = 1 y = ½ thus at this point it is...
