Answer:
cccccccccccccccccccccccc
Step-by-step explanation:
A trapezoid is a quadrilateral that has two parallel sides with a height.
<h3>The proof for trapezoid</h3>
From the diagram, AK = 1/2(AD-BC)
The combination of the bases of the equilateral triangle and the parallelogram is = the base of the trapezoid.
Therefore, BC = AD - 2AK
Make AK the subject of formula,
AK= 1/2 (AD -BC)
- From the second equation given,
KD = 1/2(AD - BC). This is wrong because of the following,
BC is parallel to KD.
Therefore length of KD = BC - AK and not KD = 1/2(AD - BC).

Answer:
24.5
Step-by-step explanation:
The mean is calculated as
mean =
The consecutive terms in the sequence have a common difference d
d = 7 - 2 = 12 - 7 = 17 - 12 = 5
This indicates the sequence is arithmetic with sum to n terms
= [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 5 , thus
= [ (2 × 2) + (9 × 5) ]
= 5(4 + 45)
= 5 × 49 = 245 , then
mean = = 24.5
