2b is basically 2 * b. When a number (called the coefficient) and a variable come together they multiply.
Answer:
Option 2
Step-by-step explanation:
6(a)-6(3)=6a-6×3=6(a-3)
Since the measure of angles adds up to 180, you should add all of the known angles up and subtract from 180 to find the missing angle. For example: 47+69=116
and
180-116=64 so the measure of the missing angle is 64 degrees
85+42= 127
180-127=53 s the measure of the missing angle is 53
