Anon25 [30]

The fact that alternate interior angles MNR and QMN are congruent to each other and vertical angles SNL and MNR are congruent to each other would help Kari prove that the measure of angle QMN is equal to the measure of angle SNL. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

(cos x - (sqrt 2)/2)(sec x -1)=0
Darya [45]

(\cos x-\frac{\sqrt{2}}{2})(\sec x-1)=0 [/tex]

=(\cos x-\frac{1}{\sqrt{2}})(\sec x-1)=0 [/tex]

\frac{(\sqrt{2}\cos x-1)}{\sqrt{2}}(\frac{1}{\cos x\ }-1)=0

(Reciprocal Identity)

(\frac{^{\sqrt{2}\\cos  x-1}}{^{\sqrt{2}}})(\frac{1-\cos x}{\cos x})=0

\frac{^{(\sqrt{2}\cos x-1})}{\sqrt{2}}\frac{(1-\cos x)}{\cos x}=0

(\sqrt{2}\cos x-1}){(1-\cos x)}=0 (ZeroProduct Property)

\sqrt{2}\cos x-1=0

\sqrt{2}\cos x=1

\cos x=\frac{1}{\sqrt{2}}

x=\frac{\Pi }{4}

and

1-\cos x=0

\cos x=1

x=0

x=0 and x=\frac{\Pi }{4} are the solutions.

What is the value of c in the equation 2(x-3)+9=3(x+1)+x
lianna [129]

Answer:

x = 0  (I must assume you had a typo since c is not a variable in this equation!

Step-by-step explanation:

Solve for x:

2 (x - 3) + 9 = 3 (x + 1) + x

2 (x - 3) = 2 x - 6:

2 x - 6 + 9 = 3 (x + 1) + x

Grouping like terms, 2 x - 6 + 9 = 2 x + (-6 + 9):

2 x + (-6 + 9) = 3 (x + 1) + x

9 - 6 = 3:

2 x + 3 = 3 (x + 1) + x

3 (x + 1) = 3 x + 3:

2 x + 3 = 3 x + 3 + x

Grouping like terms, 3 x + x + 3 = (3 x + x) + 3:

2 x + 3 = (3 x + x) + 3

3 x + x = 4 x:

2 x + 3 = 4 x + 3

Subtract 4 x from both sides:

(2 x - 4 x) + 3 = (4 x - 4 x) + 3

2 x - 4 x = -2 x:

-2 x + 3 = (4 x - 4 x) + 3

4 x - 4 x = 0:

3 - 2 x = 3

Subtract 3 from both sides:

(3 - 3) - 2 x = 3 - 3

3 - 3 = 0:

-2 x = 3 - 3

3 - 3 = 0:

-2 x = 0

Divide both sides of -2 x = 0 by -2:

(-2 x)/(-2) = 0/(-2)

(-2)/(-2) = 1:

x = 0/(-2)

0/(-2) = 0:

Answer:  x = 0
