Without using a calculator how do you evaluate tan 5π/6.

1 answer:

3 0

Remember that pi=180,
so 180/6=30, 30*5=150,
what's tan 150?
Remember that 150 degrees is in the 2nd quadrant, and this is tangent, so it means the answer must be negative, because tan 150= - tan 30, and -tan30=-√3/3.

Answer: -√3/3.

What is the slope of the line in the graph? Options: -4/3 -3/4 3/4 4/3

Marina CMI [18]

Answer:

Option 2: -¾

Step-by-step explanation:

First identify 2 points on the line.

(0, 1), (4, -2)

Substitute the coordinates into the gradient formula below:

$\boxed{gradient = \frac{y1 - y2}{x1 - x2} }$

☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate.

Slope of the line

$= \frac{1 - ( - 2)}{0 - 4}$

$= \frac{1 + 2}{ - 4}$

$= - \frac{3}{4}$

☆ Since the line is sloping downwards looking from the left to right, the line must have a negative slope.
