Answer:
117
Explanation:
Okay, the problem is asking that we find the hypotenuse of this triangle (AKA, the lake.)
a²+b²=c²
A= 75
B= 90
C is always the hypotenuse.
75²+90²= c²
5,625+8,100= 13,725
√13,725= 117.15374513859981591194584103639
To the nearest whole number: 117
To the nearest tenth: 117.2
Hope this helps!
