Step-by-step explanation:
I got my answer by multiplying the sea level he descended to the number of time he descended.
<u>Answer:</u>
<h2>
18.38</h2>
<u>Explanation:</u>
since this triangle is a right-angled triangle and one its angles equals 45° then it's an <u>isosceles right triangle</u> which means that the side opposite 45° <em>(the side to the left)</em> is equal to 13 too.
so according to pythagoras theorem c = √(a²+b²)
x =√(13²+13²)
x = √(169+169)
x = √338
x ≈ 18.38
<em>note:</em><em> in the question it's mentioned to find y! and I believe it is just an error! it's about to find x and that's more resonable!</em>
I think the answer is 4 over 7
Answer:
Width = 4 m, Length = 16 m
Step-by-step explanation:
Perimeter = 40
Width = x
Length = 3x + 4
x + x + 3x + 3x + 4 + 4 = 8x + 8
40 - 8 = 32
32/8 = x
x = 4
Width = 4
Length = 16
