Hi there!

\large\boxed{tan\text{ } (\frac{-\pi }{6})}

**Recall that tangent is Opposite / Adjacent**

tan (5π / 6) according to the unit circle equals -1 / √3. We can go through each choice and eliminate:

  • tan (-5π / 6) is in the third quadrant which would mean that the value would be positive 1 / √3. This choice is incorrect.

  • tan (7π / 6) is the same as tan (-5π / 6), which is positive 1 / √3. This choice is incorrect.

  • cot (5π / 6) is the reciprocal of tan 5π / 6, which is incorrect.

  • tan (-π / 6) is equal to -1 / √3. This choice is correct.

Therefore, the correct choice is tan (-π / 6).

Given:

The equation of line p is

y=-\dfrac{1}{3}x-3

Line p and q are parallel.

To find:

The equation of line q.

Solution:

The slope intercept form of a line is

y=mx+b

Where, m is slope and b is y-intercept.

The equation of line p is

y=-\dfrac{1}{3}x-3

The slope of the line is -\dfrac{1}{3}.

We know that the slopes of parallel lines are equal.

Line p and q are parallel. So,

Slope of line q = -\dfrac{1}{3}

Line q passes through (6,-4) with slope -\dfrac{1}{3}, so the equation of the line is

(y-y_1)=m(x-x_1)

Where, m is the slope.

(y-(-4))=-\dfrac{1}{3}(x-6)

y+4=-\dfrac{1}{3}x+2

y=-\dfrac{1}{3}x+2-4

y=-\dfrac{1}{3}x-2

Therefore, the equation of line q is y=-\dfrac{1}{3}x-2.

Answer 1, 2, and 3.
Rudik [331]

Answer:

1.

a) isosceles right triangle

b) scalene triangle

c) isosceles triangle

d) equilateral triangle

2. 53 degrees

3. Yes. You can use the side-side-side (SSS) postulate because side QR and side SR are shown as congruent, and side QP and SP are also congruent. Since you know that the other two sides are congruent, then that means that the last side must be congruent as well.

Please solve rational inequality and express in an interval notation<br> x-8/x+7&gt;0
Rudik [331]
X^2+7x-8>0 eliminating denominator Factoring (x+8)(x-1) must be positive so Case 1 both positive is x>-8 and x>1. For both to occur x>1 Case 2 both are negative (x+8)<0 and (x-1)<0 so x<-8 and x<1. For both to occur x<-8 Therefore x<-8 or x>1
