A triangle always adds up to 180 degrees total. Therefore the triangle is 70 + 26 + C = 180. Solving for C you would get 84 degrees.
Answer:

Explanation:
Here, we want to check if the given statement is a statistic or a parameter
While a parameter describes the whole population, a statistic describes a sample
From what we have in the question, the data completely describes each set of staff in the mathematics department
Thus, we can say it is a statistic
17.5 i think I’m not sure though.
Answer:
I haven't answered a question in a while, and I'm certainly not an expert on this, however I'm pretty sure you just need a force greater than 9.8 Joules, since that is the force of gravity. So I think you have to multiply 36,000 by 9.8 and that should give you the overall force that gravity will have, then most likely anything above that. I'm sorry if this doesn't exactly help, I'm kind of confused when it comes to Physics
