Answer:
- 328 / 9
Step-by-step explanation:
- 36 + ( - 4 / 9 )
= - 36 - ( 4 / 9 )
= - 36 ( 9 / 9 ) - 4 / 9
= ( - 36 x 9 ) / 9 - ( 4 / 9 )
= ( - 324 / 9 ) - ( 4 / 9 )
= ( - 324 - 4 ) / 9
= - 328 / 9

Answer:
One of the angles in the triangle might be 50.
AND
The length of the third side must be 11cm or smaller.
Step-by-step explanation:
-The triangle might be an equilateral triangle (having all the same sides and angles). False, since the triangle sum theorem states that all angles inside of a triangle must add up to 180, so an equilateral triangle would need to have all three angles at 60 degrees.
-One of the angles in the triangle must be 120 (false; it can be anything above 90, which is not only 120)
-The length of the third side must be 11cm or smaller. (True, Triangle Inequality Theorem) 
-One of the angles in the triangle might be 50 (possibly, so very much true)
