Answer:
- (2x-10) +x +(x+10) = 180
- x = 45
- (2x-10)° = 80°
- (x+10)° = 55°
- x° = 45°
Step-by-step explanation:
The equation is an expression of the fact that <em>the sum of the angles in a triangle is 180°.</em>
(2x -10)° +x° +(x +10)° = 180°
For the purposes of the answer box, I'd leave off the degree symbol:
(2x -10) +x +(x +10) = 180
__
This simplifies to ...
4x = 180
x = 45
Then the angles (CW from top) are ...
(2·45 -10) = 80°
(45 +10)° = 55°
(45)° = 45°
Answer:
FV= 5,958.67 = 5,959
Step-by-step explanation:
Giving the following information:
Current population (Present Value)= 3,810
Growth rate (g)= 3.5% annual
Number of periods (n)= 13 years
<u>To calculate the future number of people (FV), we need to use the following formula:</u>
FV= PV*(1+i)^n
FV= 3,810*(1.035^13)
FV= 5,958.67 = 5,959
