Solve the system of equations,
lorasvet [3.4K]

Answer:

x = 21/2

y = -19/2

Step-by-step explanation:

5x - 17 = 4y + 7x

5x - 7x - 4y = 17

-2x - 4y = 17

6x + 8y = - 13

-2x - 4y = 17 | ×2 |

6x + 8y = - 13 | ×1 |

-4x - 8y = 34

6x + 8y = - 13

___________+

2x = 21

x = 21/2

-2x - 4y = 17

-2(21/2) - 4y = 17

-21 - 4y = 17

-4y = 17 + 21

-4y = 38

y = -38/4

y = -19/2

The interior angle sum of a convex polygon is 1,980°.
LenaWriter [7]

Answer: 27.69⁰

Step-by-step explanation:

Formula for finding the internal angle of a regular polygon is

( 2n - 4 )right angle triangle or

( 2n - 4 )90°, it can also be broken down by factorizing the expression since 2 is common,

( n - 2 )180 or supplementary

Now to find the value of n which correspond to the number of sides the polygon has, we equate the formula to the angle sum of the polygon.

( n - 2 ) × 180° = 1980°

open the bracket

180n° - 360° = 1980°

180n°            = 1980° + 360°

                    = 2340

To find n, divide by 180 which is the coefficient of n

               n   = ²³⁴⁰/₁₈₀

                    = 13

The polygon has 13, sides

To find the measure of each angle,

Recall, the sum total of external angle  = 360⁰

Therefore, to find the value of each of the angles, we divide 360 by n which is 13

                 ³⁶⁰/n

                = ³⁶⁰/₁₃

                = 27.69⁰
