A+44=B<br> A=1x+76<br> B=-6x+134 <br> What is the value of A?
Rashid [163]
Hi there! A = 78

A + 44 = B
We can plug in the values of A and B into the equation. We then get an equation with only one variable (x), which we can solve.

1x + 76 + 44 = - 6x + 134
Collect terms.

1x + 120 = - 6x + 134
Add 6x to both sides.

7x + 120 = 134
Subtract 120 from both sides

7x = 14
Divide both sides by 7

x = 14 / 7 = 2

A = 1x + 76
Now plug in the value of x we just found

A = 2 + 76 = 78

<h3>Answer: Choice H)  2</h3>

=============================================

Explanation:

Recall that the pythagorean trig identity is \sin^2 x + \cos^2x = 1

If we were to isolate sine, then,

\sin^2 x + \cos^2x = 1\\\\\sin^2 x = 1-\cos^2x\\\\\sin x = \sqrt{1-\cos^2x}\\\\

We don't have to worry about the plus minus because sine is positive when 0 < x < pi/2.

Through similar calculations, \cos x = \sqrt{1-\sin^2x}\\\\

Cosine is also positive in this quadrant.

-------------

So,

\frac{\sqrt{1-\cos^2x}}{\sin x}+\frac{\sqrt{1-\sin^2x}}{\cos x}\\\\\frac{\sin x}{\sin x}+\frac{\cos x}{\cos x}\\\\1+1\\\\2

Therefore,

\frac{\sqrt{1-\cos^2x}}{\sin x}+\frac{\sqrt{1-\sin^2x}}{\cos x}=2

is an identity as long as 0 < x < pi/2
