Answer:
- The third side must be between 10cm and 14 cm
Step-by-step explanation:
Let the third side be x
<u>Triangle inequality theorem: sum of the length of any two sides must be greater than the third side length:</u>
- 2 + 12 > x ⇒ x < 14
- 2 + x > 12 ⇒ x > 10
- x + 12 > 2 ⇒ x > -10, we change it to x > 0 as it should be a positive number
<u>Combined together we have:</u>
The third side must be between 10cm and 14 cm
Answer:
33º and 147º
Step-by-step explanation:
x + (x + 114) = 180
2x + 114 = 180
2x = 66
x = 33º
x + 114 = 147º
