Unknown angle problems with algebra Solve x in the diagram below

Alina [70]

Answer:

Step-by-step explanation:

Alright this is like a linear pair. All three angles add up to 180; so this is the set up:

40 + 2x + 30 + 40 = 180

2x + 110 = 180

2x = 70

x=35

Anyone know how to do trigonometry

Nata [24]

The side opposite the 30 degree angle is half of the hypotenuse.
a^2 + b^2 = c^2 =>

a^2 + (c/2)^2 = c^2
12^2 + c^2/4 = c^2
4*12^2 + c^2 - 4c^2 = 0
576 - 3c^2 = 0
- 3c^2 = - 576
c^2 = 192
c = 8√3

The large rectangle shown represents one whole . Which division expression does the purple shaded area in the model represent

Hatshy [7]

Answer: The answer is $(d)~\dfrac{1}{3}\div 4.$

Step-by-step explanation: Given in the question and the figure a large rectangle consisting of 12 squares of equal areas. We need to choose the right expression for the purple shaded area.

Considering the rectangle in the figure horizontally, there are 4 rows of 3 squares. So, in the last row, the fraction of purple shaded square is

$r_p=\dfrac{1}{3}.$

And if consider the figure vertically, then there are 3 columns of 4 squares.

Therefore, the final fraction represented by the purple shaded area is

$f_p=\dfrac{1}{3}\div4.$

Thus, the correct option is $(d)~\dfrac{1}{3}\div 4.$
