Answer:
a = 180 - b - c
Step-by-step explanation:
To solve for a variable, move all the terms to the other side except a. You move terms across an equal sign using inverses.
So subtract b and c to the other side.
The answer is A.
Use Desmos Matrix Calculator. Enter you Matrix then the equation.
First you need to put it into y=mx+b format and which is 1/2x + 2 =y. The y intercept should be b in the equation y=mx +b so y=2. The x-intercept should be when y=0 and x equals a number which is x=-4. X-intercept=-4 and y-intercept=2.
