If 90% of bodies are water weight, then we have 10% left.
76+10% = 83.6.
83.6 total.
16 because if you put 16 into a percentage it's 80. 16 divide 20 times 100 equal 80
The value of y in the triangle is 2√5
The triangle above is a right angle triangle.
Characteristics of a right angle triangle:
- One of its angle is equals to 90 degrees
- The sides can be found using Pythagoras theorem.
Using Pythagoras theorem
where
c = hypotenuse(longest side)
a and b are the 2 other legs.
Therefore,
6² = 4² + y²
36 = 16 + y²
y² = 36 - 16
y² = 20
y = √20
y = 2√5
