julia-pushkina [17]

The reference angle is the smallest angle between the terminal side and the x-axis.

$(1)\ \theta = 300^o$

300 degrees is in the 4th quadrant.

So, the reference angle is

$\alpha = 360 - \theta$

$\alpha = 360 - 300$

$\alpha = 60^o$

Hence, the reference angle of 300 degrees is 60 degrees

$(2)\ \theta = 225^o$

225 degrees is in the 3rd quadrant.

So, the reference angle is

$\alpha = \theta - 180$

$\alpha = 225 - 180$

$\alpha = 45^o$

Hence, the reference angle of 225 degrees is 45 degrees

$(3)\ \theta = 480^o$

480 degrees is in the 2nd quadrant (i.e. 480 - 360 = 120)

So, the reference angle is

$\alpha = 180 - \theta$

$\alpha = 180 - 120$

$\alpha = 60^o$

Hence, the reference angle of 480 degrees is 60 degrees

$(2)\ \theta = -210^o$

-210 degrees is in the 2nd quadrant (i.e. 360 - 210 = 150)

So, the reference angle is

$\alpha = 180 - \theta$

$\alpha = 180 - 150$

$\alpha = 30^o$

Hence, the reference angle of -210 degrees is 30 degrees

Work out the size of angle x<br> Angles <br> 50<br> 120

lbvjy [14]

Answer:

x = 70°

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

120° is an external angle of the triangle, thus

x + 50 = 120 ( subtract 50 from both sides )

x = 70

A photographic stop bath contains 160ml of pure acetic acid.

NeTakaya

Answer:

Solving for the Percent by Volume

The v/v concentration of acetic acid in the stop bath is 24.6%.

Explanation:

To answer the question, we need to identify certain information stated in the question. Let us write down what’s given:

Volume of solute = 160 mL

Volume of solution = 650 mL

Next, we need to determine what is required, in this case, the percent by volume. Now, let us look at the formula:

v/v concentration = (solute volume / volume of the solution) * 100

Solution:

Percent by Volume = (160 / 650) * 100

Percent by Volume = 0.2461538461538462 * 100

Percent by Volume = 24.61538461538462

Rounded off = 24.6%

Therefore, the final answer is 24.6%
