Answer:
The answer is 5,030 feet.
Step-by-step explanation:
It is stated that his starting point is at an elevation of 0 feet. He climbs 3.200 feet on the first day and then adds another 1.830 feet on the second day. This makes his total elevation 3,200 + 1,830 = 5.030 feet.
As he reaches the other side of the island on the 3rd day which is at an elevation of 0 feet as well, he loses all the elevation he gained on days 1 and 2, which is 5,030 feet.
I hope this answer helps.
Obtuse: b^2 + c^2 > a^2
Right: b^2 + c^2 = a^2
Acute: b^2 + c^2 < a^2
A^2 + B^2 + c^2 - 2bc*cosA
As (A), is an Obtuse cos A is Negative say 2bccosA = - k then;
a^2 = b^2 + c^2 + k
a^2 > b^2 + c^2
So, your Answer would be (B)
Hope this helps!!.!
Answer:
13.6 inches
Step-by-step explanation:
We can use Pythagorean theorem: 
Let c be the diagonal length, a for length, and b for width.
Substitute the values.

c=13.6 inches
The answer would be $35.70. 70% off would be $83.30 off of $119.
