Question

Find the size of the final unknown exterior angle in a polygon whose other exterior angles are:
51°, 84°, 48°, 27°, 65° and 68°.

Answer 1

Answer:

x=17

Step-by-step explanation:

Sum of exterior angles = 360°

Other exterior angles are 51°, 84°, 48°, 27°, 65° and 68°

Let the size of the final unknown exterior angle in a polygon be x

51°+84°+48°+27°+65°+68°+x=360°

343°+x=360°

x=360-343

x=17°

∴The size of the final exterior angle in a polygon is 17°

Answer 2

Answer:

x = 17°

Step-by-step explanation:

51°+84°+48°+27°+65°+68°+x° = 360°

343°+x = 360°

x = 360° - 343°

x = 17°
