Answer:
12 times 2 since it doubles every time I'm not that sure so if I am not correct my bads
Answer:
Step-by-step explanation:
hello :
ax+b =4x+9 so a=4 and b=9
First you would have to find the third angle in the triangle which you would do by adding 63+61 and subtracting the resulting number from the total degrees in a triangle. From there, you would calculate x and y using the knowledge that angles on a line equal 180.
I am so sorry this is the wrong answer
S= B - 72
B= B
180= B+B-72
180= 2B-72
252= 2B
126 = B
B =126
S= 126-72
S=54
