If they don't have water they can die because they breathe water.

Hey..!!

It is because people can live without food for many days but cannot without water as our body needs water for certain processes which occur in our body. Our blood needs water. Our body is made up of 75-80% water only.

Hope this helps

Find the length of MG. EGF~EML

elena-14-01-66 [18.8K]

Answer:

The length of MG = 56.

Step-by-step explanation:

Two triangles are similar if their corresponding angles are congruent and corresponding sides are proportional.

Given that: $\triangle EGF \sim \triangle EML$

From the given figure:

In $\triangle EGF$ and $\trinagle EML$

EG = $5x+2$

EF = $126$

EM = $16$

EL = $28$

By definition of similar triangle,

$\frac{EG}{EM}=\frac{EF}{EL}$ ...... (1)

Substitute the given values in equation (1) as shown below:

$\frac{5x+2}{16}=\frac{126}{28}$

$5x+2 = 4.5\times 16$

$5x+2 =72$

which implies, EG = $72$ .

Now to find the value of MG.

EG = EM+MG

$72=16+MG$

Subtract 16 from both sides, we get

$MG = 56$

Hence, the value of length of MG = 56.

Help ASAP this question is hard

stealth61 [152]

Hello,

$\displaystyle \lim_{x\rightarrow7^+} \ {(3+\sqrt{2+x})}=3+\sqrt{2+7}=3+\sqrt{9}=3+3=6\\\\ \lim_{x\rightarrow7^-} \ {(8-\sqrt{x-3})}=8-\sqrt{7-3}=8-\sqrt{4}=8-2=6$

It means that

$\text{Step 1 *** }\displaystyle \lim_{x\rightarrow7^+} \ f(x) \text{ exists and its value is }6 \\ \\\text{Step 2 *** }\displaystyle \lim_{x\rightarrow7^-} \ f(x) \text{ exists and its value is }6\\\\\text{Step 3 *** The two limits are equals so we can conclude that } \\ \\ \displaystyle \boxed{\lim_{x\rightarrow7} \ f(x) \text{ exists and its value is }6}$

Thanks

Determine whether the triangles are similar. or not.

mr Goodwill [35]

Answer:

Step-by-step explanation:

We know that ∠ $ABE$ ≅ ∠ $DBC$ because they are vertical angles, so that's one pair of congruent angles. However, we can't compare ∠ $BAE$ and ∠ $DCB$ as they have different measures, so we'll have to find the measure of either ∠ $AEB$ or ∠ $BDC$ . Let's go with the former. Using the fact that the sum of the measures of the interior angles of a triangle is $180$ °, we know that $m$ ∠ $AEB=180-(53+42)=180-95=85$ °. Now, we know that ∠ $AEB$ ≅ ∠ $DCB$ because their measures are equal. That's another pair of congruent angles. Therefore, the angles are similar by $AA$ . Hope this helps!
