Find the value of X for the given pentagon?
kolezko [41]

Answer:

x = 44°

Step-by-step explanation:

The sum of the exterior angles of any polygon my be 360°, so just add all the angles up, and subtract this from 360°.

Given a pentagon with exterior angles: 102°, 47°, 34°, and 133° with the missing angle x°.

To find the missing angle, first write an equation representing the given rule:

102° + 47° + 34° + 133° + x° = 360°

(316°) + x° = 360°

316° + x° - 316° = 360° - 316°

x° = 44°.

This way, because the rule must be true, the missing angle with this value will satisfy this:

102° + 47° + 34° + 133° + <u>44°</u> = 360°

For this topic, here are some general angle rules for polygons:

  • n is the number of sides
  • 180° (n – 2) = sum of interior angles of any polygon.
  • 180° (n – 2) / n = each interior angle of a regular polygon [all sides and or angles the same measure / congruent].
  • 360° = sum of exterior angles of any polygon.
  • 360° / n = each exterior angle of a regular polygon. [all sides and or angles the same measure / congruent].

WILL MARK BRAINLIEST IF YOU ANSWER BOTH QUESTIONS WITH SOLUTION
11Alexandr11 [23.1K]

Answer:

1. = 3xy + x - 2y - 4

2. = d^2(2c^3-8c^2d+3d^2)

Step-by-step explanation:

= 9x^2y^2 + 3x^2y - 6xy^2 - 12xy/3xy

First factor the top equation ….

= 3xy(3xy + x - 2y - 4)/3xy

If the top and the bottom both carry 3xy, you can cancel out both of them leaving you with ….

= 3xy + x - 2y - 4

= -16c^6d^6 + 64c^5d^7 - 24c^3d^8/-8c^3d^4

First factor the top equation ....

= -8c^3d^6(2c^3-8c^2d+3d^2)/-8c^3d^4

If the top and the bottom both carry -8c^3 you can cancel out both of them leaving you with ….

= <u>d^6</u>(2c^3-8c^2d+3d^2)/d^4

Apply the exponent rule with d^6 ....

= <u>d^4</u><u>d^2</u>(2c^3-8c^2d+3d^2)/d^4

cancel out d^4 ....

= d^2(2c^3-8c^2d+3d^2)
