R=23 because its slope the formula is Y-Y/X-X
Answer: b=2
Step-by-step explanation: First you will have the equation 22=11b. You need to get b by itself so you will need to divide each side by 11 which will leave you with 22/11=11/11b. After that you will be left with 2=b
The answer would be because
Answer:
a = 180 - b + c
Step-by-step explanation:
a + b - c = 180
Move b by subtracting b from both sides.
a - c = 180 - b
Move c by adding c to both sides.
a = 180 - b + c
Therefore a equals 180 - b + c.
