Answer:
The value of .
Step-by-step explanation:
Diagram of the given scenario shown below.
Given that,
Distance from bench to Jasmyn is .
Distance from bench to Willard is .
From the Question,
The given wishing well is a circle and all the distance are tangent to the circle.
So, Triangle formed by these points are such as Δ and Δ
.
Now, taking both Δ and Δ
.
⇒ {Radius of circle are equal}
⇒ {Common side}
⇒ ∠ ∠
{radius is always perpendicular
to the point of tangent }
∴ Δ ≅ Δ
{By SAS congruence theorem}
Therefore, ....(1) {corresponding part of
congruence triangle (CPCT)}
Thus,
⇒ {from equation (1)}
⇒
⇒
Hence, The value of .
