Question

please help i dont understand
Lisa and Molly are on a bridge and see a tree sticking out of the water. Use the diagram to determine how far away Lisa is from the tree in the water. Use appropriate units.

Answer 1

Answer:

Distance between Lisa and the tree in the water = 26.5 ft

Step-by-step explanation:

From the figure attached,

Lisa is a point L, Molly is at M and a tree stick at point S.

By applying sine rule in ΔLMS,

$\frac{\text{SinL}}{\text{SM}}=\frac{\text{SinM}}{LS}=\frac{\text{SinS}}{\text{LM}}$

$\frac{\text{Sin(54)}}{22}=\frac{\text{Sin(103)}}{\text{LS}}$

LS = $\frac{22\times \text{Sin}(103)}{\text{Sin(54)}}$

LS = 26.5 ft

Therefore, distance between Lisa and the tree in the water is 26.5 ft.
