Find the exact value of tan 60° in simplest form with a rational denominator.​

Mathematics

Elis [28]3 years ago
3 0

Step-by-step explanation:

We need to find the exact value of tan 60° in simplest form with a rational denominator.​

We know that, \tan\theta=\dfrac{\sin \theta}{\cos\theta}

Here, \theta=60^{\circ}

So,

\tan(60)=\dfrac{\sin (60)}{\cos(60)}\\\\=\dfrac{\dfrac{\sqrt3}{2}}{\dfrac{1}{2}}\\\\=1.73\\\\or\\\\=\dfrac{173}{100}

Hence, this is the required solution.

Write, in slope intercept form, the equation of the line that passes through (8, -9) and has a slope of -5/4.
dezoksy [38]

Answer:

The equation in the slope-intercept form will be:

y=-\frac{5}{4}x+1

Step-by-step explanation:

Given

  • slope = m = -5/4
  • point = (8, -9)

As we know that the equation of a line in point-slope form is

y-y_1=m\left(x-x_1\right)

substituting the values m = -5/4 and point = (8, -9)

y-\left(-9\right)=\frac{-5}{4}\left(x-8\right)

y+9=\frac{-5}{4}\left(x-8\right)

Writing the equation in slope-intercept form

y=mx+b

where m is the slope, and b is the y-intercept

so the equation of the line in slope-intercept form becomes

y+9=\frac{-5}{4}\left(x-8\right)

subtract 9 from both sides

y+9-9=\frac{-5}{4}\left(x-8\right)-9

y=-\frac{5}{4}x+1

Therefore, the equation in the slope-intercept form will be:

y=-\frac{5}{4}x+1

For parallelogram ABCD, find the value of x.<br> 3x + 20<br> B<br> С<br> A А<br> D<br> 5x – 12
Arlecino [84]

Answer:

x = 16

Step-by-step explanation:

5x-12=3x+20

plus 12 both sides

5x=3x+32

-3x both sides

2x=32

divide by 2 both sides

x=16
