About 0.6 of the human body is made up of water. if a person has a mass of 75 kilograms what is the mass of the water in this person body

45 kg of water

Step-by-step explanation:

About 0.6 of the human body is made up of water. if a person has a mass of 75 kilograms, we can find the mass of water by multiplying the body mass (75 kg) by the fraction of water in the human body (0.6). That is,

75 kg × 0.6 = 45 kg

A 75 kg-person has about 45 kg of water.

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.
