17. Solve for x.(9x 18)° |
|
Answer» The given figure is regular pentagon. So, all angles must be equal. We know sum of all angles in pentagon is 540°. 5 × ( 9x - 18°) = 540° 9x - 18° = 540°/5 9x - 18° = 108° 9x = 108° + 18° 9x = 126° x = 126°/9 x = 14° So, each angle is 9x - 18° = 9 ×14 - 18 = 108° Please hit like if you find my solution useful |
