Answer:
200.96
Step-by-step explanation:
3.14 x (8x8) = 200.96
1/4 (4/6 - 3/12) = 1/4 (5/12) = 5/48
Answer:
23
Step-by-step explanation:
According to the diagram, two sum of <1 and <2 is 180 degrees
Hence 3x+30+81 = 180
3x+111 = 180
3x =180-111
3x = 69
x = 69/3
x = 23
I believe it is 67. Because you distribute the plus sign and then add.
It is 2. You flip the fraction and make it negative always to get perpendicular slopes. If it was like 3, you treat it as 3/1 and would make it -1/3.
