A step-by-step would be great. Thank you.

Answer 1

BC = 143

JC = 10

Explanation:

Similar triangles:

In similar triangles, the corresponding sides are in same ratio.

ΔABC ~ ΔAGH

`\sf (BC)/(GH) = (AB)/(AG)\\\\\\(BC)/(22)=(130)/(20)\\\\`

`\sf BC =(130)/(20)*22`

= 13 * 11

`\sf \boxed{BC = 143}`

11) ΔJLK ~ ΔJBC

`\sf (JC)/(JK) = (JB)/(JL)\\\\\\(JC)/(40)=(12)/(48)\\\\JC = (12)/(48)*40\\\\JC = (1)/(4)*40\\\\JC = 1*10\\\\\boxed{\bf JC = 10}`
