Answer:

a=-2

Step-by-step explanation:

4a-14=7a-8

Subtract 7a from both sides:

4a-14-7a=7a-8-7a

Group like terms:

4a-7a-14=7a-8-7a

Simplify the arithmetic:

-3a-14=7a-8-7a

Group like terms:

-3a-14=7a=-7a-7a-8

Simplify the arithmetic:

-3a-14=-8

Add 14 to both sides:

-3a-14+14=-8+14

Simplify the arithmetic:

-3a=-8+14

Simplify the arithmetic:

-3a=6

Divide both sides by-3:

Cancel out the negatives:

Simplify the fraction:

Simplify the signs:

Find the greatest common factor of the numerator and denominator:

Factor out and cancel the greatest common factor:

Can someone help me?

Answer:

Step-by-step explanation:

To do this, we must use the unit circle. At the angle $\frac{\pi }{6}$ the coordinate pair is ( $\frac{\sqrt{3} }{2}$ , $\frac{1}{2}$ ) and the hypotenuse is 1

Now that we know these we can start using the trig functions

sin = y

cos = x

tan = $\frac{y}{x}$

And the other functions would be the reciprocal of these

csc = $\frac{1}{y}$

sec = $\frac{1}{x}$

cot = $\frac{x}{y}$

This would mean that

sinx = $\frac{1}{2}$

cosx = $\frac{\sqrt{3} }{2}$

tanx = $\frac{1}{\sqrt{3} }$ or $\frac{\sqrt{3} }{3}$ if you're supposed to rationalize your denominators

cscx = 2

secx = $\frac{2}{\sqrt{3} }$ or $\frac{2\sqrt{3} }{3}$

cot = $\sqrt{3}$
