Answer:
C. 6.736
Step-by-step explanation:
The unmarked angle is 180-80-40 = 60 degrees. Given the angles of the triangle and one side length there is enough information to use the Law of Sines to solve the triangle--eliminating choice D.
The angle opposite x is larger than the angle opposite 5, so <em>x will be larger than 5</em>. That leaves only answer choice C: 6.736.
___
If you want to actually use the law of sines to determine x, you know that ...
x / sin(60°) = 5 / sin(40°)
x = 5·sin(60°)/sin(40°) . . . . . . multiply by sin(60°)
x ≈ 6.736
To answer this item, we assume that the topic is in similar polygons such that the ratio of the corresponding sides should be equal. In this item,
BY/YC = AX/XC
Substituting the known values,
6/10 = 18/XC
The value of XC from the equation is 30. The answer is letter C.

Step-by-step explanation:
The vote goes half and half: 7 draw, 7 other activities.
Half and half of 20 students works out to 10 draw, 10 engage in other activities.
Answer:
So the answer should be 1/4.
Step-by-step explanation:
so a cube has all equal sides and volume is equal to s^3 or side*side*side in this case 1/2*1/2*1/2. There are two cubes so you would multiply that by two creating 2*1/2*1/2*1/2
Hope this helps :)

Answer:
Hope it works for u
Step-by-step explanation:
As we have given two shapes bathroom
square and rectangle
Parameter of square= sum of all the sides ( : In square all sides are equal
Parameter of square= 4*L = 4*(x+3) (:L=x+3
similarly,
In rectangle opposites sides are equal hence
Perimeter of rectangle= 2*length+2*width ( : length=x+4,width can't be seen clearly so I assume and take it width=x+1 hope this is equal to the width of ur question otherwise do the calculation by ur self).
Perimeter of rectangle= 2*(x+4)+2(x+1)
so now we have to find the value of "x" for which both perimeter are equal, so
perimeter of square= perimeter of rectangle
4*(x+3)=2*(x+4)+2(x+1) we can also write as
<h2>
2(x+3)+2(x+3)=2(x+4)+2(x+1)</h2><h3>
This is the linear equation required</h3><h3>
now to find value of "x"</h3><h3>
simplify both sides, we get</h3><h3>
4x+12=4x+10</h3><h2>
0≠2 so that not true and also there is no value of "x"</h2>
for which both parameters become equal
<h2>
so from my side "b" option is correct</h2>
Please brain-list it if u find it help-full it requires effort!
