The basic definition of a perimeter is the boundary line of an object. For shapes and figures, this is basically the sum of the outermost sides that define the object. Since an octagon has eight sides, with each side measuring 12m, the perimeter can be obtained by multiplying 12 m by 8 sides, or in equation form:
P = 8(12)
Among the choices, this is letter B.
Answer:
20 degrees
Step-by-step explanation:
9 - (-11) = 20 degrees
The height is 8 root 3 (sqrt(192)). 8 root 6 = 1/2 * 2 root 2 * x. Simplifying this gives us 8 root 6 = sqrt 2 *x. Square both sides and 64*6=2*x^2 further simplifying gives 192 = x^2, so take the squart root of both sides to get sqrt(192) which is equal to 8 root 3.
Answer:
64 ways
Step-by-step explanation:
Let n = 8
The number of ways a person can take one stair = n^P1 = 8^P1
The number of ways a person can take two stairs = n^P2 = 8^P2
∴ The number of ways the person who can take one stair or two stairs at a time = 8^P1 + 8^P2 = 8 + 56 = 64 ways
