I believe it would be the second option, B. I hope this helps! ^^
Answer:
8x + 12 + 2x + 28 = 180
Step-by-step explanation:
just add the angles ABC and CBD then equates to 180
8x + 12 + 2x + 28 = 180
10x = 180 - 12 - 28
x = 140/10
x = 14
therefore, the equation to solve x :
8x + 12 + 2x + 28 = 180
The length of each leg is unknown is first you would have to figure out how long each leg is, one leg is 30ft because of the 30ft on the other side. But since we don't know how long the top is we have to do 70 - 30 which is 40 now that we have both legs we can use the Pythagorean theorem 30^2 + 40^2 = c^2 the answer is 2500 and if we square it we get 50 hope this helps :)
Answer:
The surface area of a cube is 6s2 where s is the length of an edge. If 6s2 = 384, then we can solve this to fund that s = 8.
Step-by-step explanation:
X is equal to 11/30 because, using basic moves, you subtract the 2 4/5 from either side to get x by itself. So 3 1/6 - 2 4/5 = 11/30. Then you are left with x = 11/30.
