Identify the lengths of QS and SR
1 answer:
<span>The bisector of an angle of a triangle divides the opposite side into segments that are proportional to the adjacent sides </span>⇒ <span> 10/12 = (3x+2)/(5x-0.4) 10(5x-0.4) = 12(3x+2) 50x - 4 = 36x + 24 50x - 36x = 24 + 4 14x = 28 x = 28/14 x = 2 QS = 3x + 2 = 3*2 + 2 = 6 + 2 = 8 SR = 5x - 0.4 = 5*2 - 0.4 = 10 - 0.4 = 9.6 Answer is QS=8, SR=9.6 </span><span> </span>
