Triangle ABC is an equilateral triangle with side lengths labeled a, b, and c. Triangle A B C is an equilateral triangle. The le

ngth of side A B is c, the length of B C is a, and the length of A C is b. Trigonometric area formula: Area = One-half a b sine (C) Which expressions represent the area of triangle ABC? Select three options. a c sine (60 degrees) One-half b c sine (60 degrees) One-half a squared sine (60 degrees) StartFraction a squared b sine (60 degrees) Over 2 EndFraction StartFraction a b sine (60 degrees) Over 2 EndFraction

Answer:

One-half b c sine (60 degrees)

One-half a squared sine (60 degrees)

StartFraction a b sine (60 degrees) Over 2 EndFraction

Explanation:

The area rule states that the area of any triangle is equal to half the product of the lengths of the two sides of the triangle multiplied by the sine of the angle included by the two sides.

From the question, Equilateral triangle refer to a triangle with equal angle and equal sides. The sum of an angle in a triangle = 180°; this implies that each angles have 60°.

∴ the three options that defines the expressions that represent the are of triangle ABC are:

One-half b c sine (60 degrees)  

i.e \frac{1}{2}bcsin60^{0}

One-half a squared sine (60 degrees) ; if the two opposite sides posses the same parameters.

i.e \frac{1}{2}a^{2}sin60^{0}

StartFraction a b sine (60 degrees) Over 2 EndFraction

i.e \frac{absin60^{0}}{2}

Select the correct answer. Which statement correctly explains the polarity of the water molecule? A. The hydrogen end of the mol
Nuetrik [128]

Answer:

option B) The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.

Justification:

The electronegativity of an element accounts for its relative ability to attract electrons.

Being oxygen more electronegative than hdyrogen (the electronegativity of oxygen is 3.44 while the electronegativity of the hydrogen is 2.20), the electron density will be displaced toward the oxygen, letting it with a partial negative charge and the hydrogen with a partial positive charge.

Finally, since the charge is not symmetrical distributed around a center of the molecule, the molecule ends being polar.
