(Inequalities) what do you have to do when multiplying or dividing by a negative number?
Rashid [163]

Answer:

When we multiply or divide by a negative to solve an inequality, it's the same as multiplying or dividing by a negative to solve a regular equation! Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative <u>YOU MUST FLIP THE INEQUALITY SIGN.</u>

Step-by-step explanation:

You are welcome.

And I hope this helps.      :)

<h3>What is a triangle? </h3>

A triangle is a polygon with three sides and vertices. The sum of angles in a triangle is 180 degrees. Types of triangles include: right-angled triangle, isosceles triangle, equilateral triangle and scalene triangle.

<h3>What is the measure of the largest angle? </h3>

The measure of the largest angle = (largest ratio / sum of ratios) x 180

10 / 24 x 180 = 75 degrees

If cos(Θ) = -2 9 , and 90° &lt; θ &lt; 180°, what is the value of tan(θ)?
frosja888 [35]
We know that

if  <span>90° < θ < 180°
</span>then
θ--------------> belong to the second quadrant
so
tan θ is negative

sin² θ + cos² θ=1----------> sin² θ=1-cos² θ----->sin² θ=1-(-2/9)²
sin² θ=1-(4/81)------> 77/81----------> sin θ=√(77/81)------> √77/9
sin θ=(√77)/9

tan θ=sin θ/cos θ------> [(√77)/9]/[-2/9]-------> -√77/2

the answer is the option
<span>A) -77sqroot/2</span>
