Answer:The first option (5.7km)

Step-by-step explanation:Since we have a right angle triangle and we know two of its sides we can easily find out the thirds side (the value of d) by using the Pathagoras Theorem. In our case 7 and d are our legs and the hypotenuse is equal to 9, so…

(Based on the Pathagoras Theorem)

d ≈ 5.7km

There for aproximate distance across the lake is equal to 5.7km

Answer:A
