Question

the side triangle are 8 ,15, 17.find the triangle also find the length of alt drawn on the side with length 17?​

Answer 1

Step-by-step explanation:

$s = \frac{8 +15 +17}{2} \\ s = 20 \\ \\ area = \sqrt{s(s - a)(s -b )( s- c)} \\ \: \: \: \: \: \: \: \: \: \: = \sqrt{20 \times 12 \times 5 \times 3} \\ \: \: \: \: \: \: \: \: \: \: = 60$

$area = \frac{1}{2} \times base \times altitude$

60= 1/2 × 17 × alt

alt = 60×2/17

alt =120/17=7.0588...
