Answer:
Triangle
Step-by-step explanation:
A triangle has three vertexes, and therefore three interior angles. Those angles also sum to 180 degrees because of the formula (n-2)*180, where n is the number of sides that a polygon has. Plugging in 3, you get 
, or just 180 degrees. Hope this helps!
Answer:
x= 8
Step-by-step explanation:
5.5(x-3)=17+10.5
5.5x - 16.5= 27.5
5.5x= 44
x= 8
Answer:
A
Step-by-step explanation:
Given
= 30 ( square both sides to clear the radical )
qrv + 11 = 900 ( subtract 11 from both sides )
qrv = 889 ( divide both sides by rv )
q = 
→ A
Force = mass * acceleration
Force = 0.3 km * 8m = 2.4 N
