Answer:

π/6

Step-by-step explanation:

if             tan(pi/16) = squareroot(3)/3

then        tan^-1(squareroot(3)/3) = pi/6

Answer:

150˚ or 330˚

Step-by-step explanation:

It is easier to use the calculator, but you can use the unit circle too.

Calculator:

Plug in the equation without the negative, and you get 30˚ which is your reference angle. But since tangent is negative, the angle is in either the second quadrant, or the fourth (because tangent is negative in these quadrants). Now using your reference angle, you can find the answer.

Slope <br>y intercept <br>x intercept​
nalin [4]

Answer:

Step-by-step explanation:

y = mx + b

Here, m is the slope.

b is the y-intercept

x-intercept = -b/m

y = 3x -4

a) slope = 3

b) y-intercept = (-4)

c)  x -intercept = -(-4)/3 = 4/3

y = \frac{1}{5}x-3

a) slope =  \frac{1}{5}

b) y-intercept = (-3)

c)  x -intercept = -\frac{1}{5}÷(-3)

                      = \frac{-1}{5}*\frac{-1}{3}\\\\=\frac{1}{15}

Triangles PQR and RST are similar right triangles.
loris [4]

Answer:

A. \frac{3 - 7}{-4 -(-7)} = \frac{-5 - 3}{2 - (-4)}

Step-by-step explanation:

Slope of PR = \frac{y_2 - y_1}{x_2 - x_1}

Where,

P(-7, 7) = (x_1, y_1)

R(-4, 3) = (x_2, y_2)

Slope of PR = \frac{3 - 7}{-4 -(-7)}

Slope of RT = \frac{y_2 - y_1}{x_2 - x_1}

Where,

R(-4, 3) = (x_1, y_1)

T(2, -5) = (x_2, y_2)

Slope of RT = \frac{-5 - 3}{2 - (-4)}

Therefore, the proportion that can be used to show that the slope of PR = the slope of RT is:

\frac{3 - 7}{-4 -(-7)} = \frac{-5 - 3}{2 - (-4)}
