Solve the formula 180=a+b+c for a

Mathematics
1 answer:
navik [9.2K]3 years ago
8 0

Answer:

a = 180 - b - c

Step-by-step explanation:

given 180 = a + b + c or

a + b + c = 180 ( isolate a by subtracting b from both sides then c )

subtract b from both sides

a + c = 180 - b

subtract c from both sides

a = 180 - b - c

1) Those are polar coordinates

2) The expression inside cosine is the angle of the vector to be drawn

3) r is the length of the vector to be drawn.

For example:

- if you take angle =0 and r results to be =2, it means that you have to put a point over the x-axis at a distance of two units from the origin.

4) You have to look for notable values, like points on the axis and notable angles (0, 45°, 90°, 180 °,...)

5) Use derivation to find maximum and minimum values. 

6) The graph of this function looks like the infinite symbol: ∞

7) Some notable points are: (0,0) ; (0,2) ; (0, - 2)

See attached the complete graph as a reference.
