Angles help find values

Answers

Answer 1

Answer:
Here's the rule. I'm SURE you learned it in Middle School. Or,
I guess I should say: I'm SURE it was taught in Middle School.

Vertical angles are equal.

"Vertical angles" are the pair of angles that don't share a side,
formed by two intersecting lines.

AND ... even if you forgot it since hearing it in Middle School,
it was clearly explained in the answer to the question that
you posted 9 minutes before this one.

In #8, 'x' and 'z' are vertical angles.
'y' and 116° are vertical angles.

In #9, 'B' and 131° are vertical angles.

In #10, 'B' and 135° are vertical angles.

For all of these, it'll also help you to remember that all the angles
on one side of any straight line add up to 180°.

Answer 2

Answer: Angles around a point = 360°
Opposite angles are the same

8. y=116°
   x=64°
   z=64°

9.B=131°
   x=49°

10.B=135°
     x=45°

Cost of a dozen eggs depends on the size of the eggs. what is the dependent variable?

Answers

the cost of the eggs
cost (x) = x*price
this is an example of a proportional cost relation with the size been x

Answer: the dependent variable is the cost of a dozen of eggs.

Explanation:

The cost is function of the size of the eggs, Cost = f (size).

That means that you introduce the size (this is the input) in the function an you obtain the cost (this is the output)

The input is the independent variable and the output is the dependent variable.

The adjacent sides of a parallelogram measure 14 centimeters and 20 centimeters, and one angle measures 57°. Find the area of the parallelogram.

Answers

The area of an isosceles triangle is given by

$Area = base \: * height$
We have the base already given, so we just have to calculate the height using the sine ratio.

$\sin(57 \degree) = (h)/(14)$
$\Rightarrow h = 14 * \sin(57 \degree)$

You may choose to use your calculator here, but I will prefer to keep it as it is and use the calculator value at the end.

Now let's plug our values inside the formula, yo obtain,

$Area = 20 * 14 \sin(57 \degree)$
$Area = 234.8 {cm}^(2)$

$<b>Hence, the area of the parallelogram is 234.8cm²</b>$

Hello,
Let's h the height of the parallelogram:
sin 57°=h/14==> h=11,741387...
Area=h*20=234,827759... (cm²)
