Answer: always
Step-by-step explanation:
The angles in a triangle add up to 180 degrees. If one angle is 90 degrees or more, the other two have to split the remaining 90 or less.
Answer:

Step-by-step explanation:
Given
Force directly proportional to acceleration
Force = 21N when Acceleraion = 7m/s^2
Required
Determine the force when acceleration = 9m/s^2
The variation between force (F) and acceleration (A) implies that:

Convert to an equation

Where m is constant.
When F = 21 and A = 7, we have:

Solve for m


When A = 9
Substitute 9 for A and 3 for m in 


I would say yes and no because estimations aren't exact, they're close to the correct value. Trent's estimation is correct since 53+12=65, if we were looking for the exact distance, Trent would be wrong because there are fractions too, so the exact value would be 66 (5/12) or 65 (17/12).
Hope this helped :)
