Answer:
117
Step-by-step 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!

Answer:
ADE=59º
Step-by-step explanation:
4x+15+13x+7=90
17x+22=90
17x=68
x=4
angle B=angle ADE so we plug in x=4 into 13x+7
13(4)+7=59º
