Answer:
140 degrees
Step-by-step explanation:
The center angle of a semi circumference is 180 degrees
BC 180 - 20 - 20 = 180 - 40 = 140 degrees
To find the area multiply length times width.
43 times 36 is 1548
Take 1548 divide by 172 to get the answer.
1548/172 equals 9
Answer:
6+3
Step-by-step explanation:

Now add 48/8 to 7/8 to get 55/8
