Find the value of X<br> please help!
denis23 [38]

Answer:

Step-by-step explanation:

So the first thing to do is get the number of angles inside this pentagon, which is 540 degrees. One way to do this is that you know a pentagon is formed of 3 triangles and since there are 180 degrees in a triangle, 3x180=540

Then it is algebra

540=91+125+92+(3x-5)+(4x-8)

Simplify what you can and collect like terms

540=308+3x-5+4x-8

540=308+7x-13

Then move everything over to the one side so that the variable is isolated

540-308+13=7x

245=7x

242/7=x

35=x

A point is randomly chosen in the diagram shown below. What is the likelihood that a point chosen inside the square will also be
s2008m [1.1K]
Side of the square: s
Area of the square: As=s^2

Diameter of the circle: d=s
Area of the circle: Ac=pi d^2/4
Ac=pi s^2/4; pi=3.1416
Ac=3.1416 s^2/4
Ac=0.7854 s^2

<span>The likelihood that a point chosen inside the square will also be inside the circle: P=?
P=Ac/As=0.7854 s^2 / s^2
P=0.7854
P=0.7854 * 100%
P=78.54%

</span>The likelihood that a point chosen inside the square will also be inside the circle is 0.7854 or 78.54%

Answer:

Length of base (a) = 5 units

Total Surface Area of Pyramid (T.S.A.) = ?

Now,

T.S.A. = Area of four triangles + Area of base

         = 4(\frac{\sqrt{3} }{4})(5^{2}) + 5^{2} = 25\sqrt{3}  + 25 ≈ 68.301sq. units
