Let vertex is x Basa angles are 2x We know that Sum of angles in triangle is 180 X+2x+2x=180 5x= 180 X=36 Base angle=2(36) =72 Exterior angles = sum of interior angles =72+72 =144

Estimate the square root of 72 how to find it
Take 1st equation 2m-3p-n=0 Take 2nd equation 2m-5p-n=14 ---------- now exchnage signs of the 2nd equation and do adition with changed signs. 2m -3p -n= 0 2m -5p -n= 14 (-) (+) (+) (-) -------------------- 2p = -14 p = -7 value of p is -7
Take n=1 6^1+4 =>10 which is divisible by 5. 6^n+4 is divisible by 5 for all nEN. Take n= n+1 6^n+1 +4 => 6^n*6 +4 => 6[6^n +4] as 6^n+4 is divisible by 5 for all nEN 6*[multiples of 5] also divisible by 5 Hence 6^n+4 is divisible by 5 for all nEN.
