Step-by-step explanation:
Answer:
It is an acute triangle.
Step-by-step explanation:
It would be much easier for you to see where I'm getting at if you draw a diagram.
Assume this triangle is labelled ABC where a = 14, b = 21, and c = 16.
cos A = (16^2 + 21^2 - 14^2)/(2(16)(21))
∠A = cos^-1(0.82291...)
∠A ≅ 34.6°
cos B = 16^2 + 14^2 - 21^2)/(2(16)(14))
∠B = cos^-1(0.024...)
∠B ≅ 56.8°
∠C = 180 - (∠A + ∠B)
∠C ≅ 56.8°
Since there is no right-angle nor is there an obtuse angle,
Therefore the triangle is an acute triangle.

Answer: 36 people
Step-by-step explanation:
1. The number of people that aspire to become doctor is:
360 people*0.65=234 people
2. The number of people that aspire to become police is:
360 people*0.05=18 people
3. The number of people that aspire to become pilot is:
360 people*0.2=72
4. The sum of people that do not aspire to become entrepreneurs is:
234 people+18 people+72 people=324 people
5. Therefore, the number of people that aspire to become entrepreneurs is:
360 people-324 people=36 people
Answer:
74
Step-by-step explanation:
Using PEMDAS we can see that we need to do the parentheses first.
After that we need to add the answers together.
This gives us our answer of 74.
