The value of interior angle x for the given pentagon if found as 88 degrees.
<h3>What is termed as the pentagon?</h3>
- A pentagon is a two-dimensional polygon with 5 sides and 5 angles.
- This shape should have five sides and form a closed two-dimensional figure.
- A closed figure consists of each of its sides intersecting to form vertices.
- Five diagonals connect the five vertices to one‘s opposite vertices in a pentagon shape.
- Each interior angle in a regular pentagon is 108°, so each exterior angle is 72°.
For the given question;
The exterior angles of the pentagon are given in figure.
Find all the interior angles for given angles using linear pair as all are straight lines.
- 180 - 62 = 118
- 180 - 33 = 147
- 180 - 114 = 66
- 180 - 59 = 121
The sum of all the interior angle of pentagon is 540.
Thus,
118 + 147 + 66 + 121 + x = 540
x = 540 - 452
x = 88
Thus, the value of interior angle x for the given pentagon if found as 88 degrees.

So we know that surface area is top circle +bottom circle+ (circumfurence times height so) 2(π(radius)^2)+(height(2π(r))) so fill in the blanks
it's kind of hard to see but πr means pi times radius (r)
2πr^2+((4.2)(2)(π)(r))=628.3
factor out the 2 so the equation would mean
2((πr^2)+(4.2πr))=628.3
divide both sides by 2
πr^2+4.2πr=314.15
what's interesting is that the first few digits of pi are 3.1415 so we aproximate pi as 3.14 and divide both sides by 3.1415
r^2+4.2r=100
subtract 100 from both sides
r^2+4.2r-100=0
factor
(x-8.11812)(x+12.3181)=0
so (if xy=0 then x or/and y must be 0 so)we set them to 0 so
x-8.11812=0
x=8.11812
second one
x+12.3181=0
x=-12.3181
since radii (or any legnth) cannot be negative, we can cross this solution out so
radius=8.11812
One is 17.22 and the other is simply 2.
