Question

WILL GIVE BRAINLIEST, please help! Calculate JK if LJ = 39, JM = 80, and LM = 89 (Hint: Use proportions)

Answer 1

Answer:

≈ 18.46

Step-by-step explanation:

LJ = 39, JM = 80, and LM = 89

JK= x ⇒ KL= 39-x

JM/LM= x/(39-x)

• 80/89=x/(39-x)
• 89x= 80*(39-x)
• 89x+80x= 80*39
• 169x= 3120
• x= 3120/169
• x≈ 18.46
