Answer:
x = 127°
x = 36
Explanation:
For the question 5:
The sum of interior angles for the given geometrical figure is calculated with the following formula:
(s-2) × 180
- s is the number of sides/angles.
3 × 180 = 540
- Find the sum of all angles.
90 + 143 + 77 + 103 + x = 540
413 + x = 540
- Subtract 413 from both sides to isolate x.
x = 127°
For the question 6:
The given is a hexagon. The sum of its exterior angles is equal to 360.
- Find the sum of the given angles to find the value of x.
80 + 59 + 2x + 59 + 54 + x = 360
252 + 3x = 360
- Subtract 252 from both sides to isolate x.
3x = 108
x = 36
