What is x=? I got part a but what does x=?

Mathematics
1 answer:
Oksi-84 [34.3K]3 years ago
3 0

Answer:

I think x = 44°

Step-by-step explanation:

Finding the exterior angle:

180° - 45° = 135°

We know that x is multiplied by 3 (3x) so we divide 135 by 3.

135° / 3 = 45°

We know that we have to add 3° to the product of 3x, so we know the product of 3x will be less than 135°. The product should be 135° after 3° is added to it.

Trying a few possible answers:

43° × 3 = 129°

129° + 3° = 132°

That one wasn't quite right.

44° × 3 = 132°

132° + 3° = 135°

:D

4x and 2x line along a straight line, their sum then must be 180° so

6x=180

x=30

So the angles in there are:

3(30)-5=85°

2(30)=60°

4(30)=120°

What is the correct equilibrium constant expression for this equation? 2 upper C upper o upper F subscript 2 (g) double arrow up
Alekssandra [29.7K]

The correct equilibrium constant expression for this equation is;

\rm K_{eq}=\dfrac{(C0_2)(CF_4)}{(COF_2)^2}

Given

Consider the equation below.

\rm {2COF_2(g)}\rightleftharpoons C0_2(g)+CF_4(g)

<h3>What are Species?</h3>

In an equilibrium constant expression, you do not include the solid substances; only gases and dissolved substances.

<h3>Equilibrium constant expression;</h3>

It is the quotient of the product of the concentrations of the species on the right-hand side of the equilibrium equation, each raised to its corresponding coefficient, and the product of the concentrations of the species on the left-hand side, each raised to its corresponding coefficient.

Therefore,

The correct equilibrium constant expression for this equation is;

\rm K_{eq}=\dfrac{(C0_2)(CF_4)}{(COF_2)^2}

Hence, the correct equilibrium constant expression for this equation is;

\rm K_{eq}=\dfrac{(C0_2)(CF_4)}{(COF_2)^2}.
