The area of triangle LMN is 18 ft2 and the area of FGH is 24 ft2. If triangle LMN is equivalent to triangle FGH, what is the rat

Sedaia [141]

Answer: Option 'C' is correct.

Explanation:

Since we have given that

Area of triangle LMN = 18 ft²

Area of triangle FGH = 24 ft²

Since Δ LMN and ΔFGH is equivalent triangles.

As we know the theorem which states that ratio of areas of equivalent triangles is equal to square of ratio of corresponding sides.

So, it becomes,

$\dfrac{\Delta LMN}{\Delta FGH}=(\dfrac{LM}{FG})^2\\\\\dfrac{18}{24}=(\dfrac{LM}{FG})^2\\\\\dfrac{3}{4}=(\dfrac{LM}{FG})^2\\\\\sqrt{\dfrac{3}{4}}=\dfrac{LM}{FG}\\\\\dfrac{\sqrt{3}}{2}=\dfrac{LM}{FG}$

Hence, Option 'C' is correct.

What is the water molecule's characteristic "bent" shape due to?

AlladinOne [14]

Answer:

Explanation:

A water molecule is made up of an oxygen molecule bonded covalently to two hydrogen atoms. Each of the hydrogen atoms shares an electron pair with the oxygen stabilizing their electron configurations to 2 and that of oxygen to 2.8. The oxygen atom will, therefore, have two extra pairs of unbonded electrons that occupy space and repel each other include the bonding pair electrons. Due to these repulsive interactions, all these electron pairs arrange themselves into a tetrahedral geometrical shape in space with the angles between the pairs being 109.5 degrees.
