Answer:
The value of BK is 3m and the value of CK is 2.4m.
Step-by-step explanation:
Given information: ABCD trapezoid
, BC=1.2m, AD=1.8m
, AB=1.5m, CD=1.2m
, AB∩CD=K.
Using the given information draw a figure.
Two sides of a trapezoid are parallel.
Since AB∩CD=K, therefore AB and CD are not parallel, because parallel line never intersect.
(Corresponding angles)
(Corresponding angles)
By AA rule of similarity
Corresponding sides of similar triangles are proportional.
The length of BK is 3 m.
The length of CK is 2.4 m.
The answer is 5 and 18. This is because 5 times five is 25. 25 minus 7 is 18.
Answer: 6 1/6 , 5.5, 4 3/8, 4.3, 3.75
Step-by-step explanation:
4.3 , 5.5 , 36, 3.75, 4.375
Answer:
3.5
Step-by-step explanation:
This is a 30-60-90 triangle so the hypotenuse is equal to 2 times 
.
≈ 3.5
Answer:
<h2>
aₙ = -3n + 8</h2>
Step-by-step explanation:
The nth term of an arithmetic sequence: aₙ = a₁ + d(n - 1)
{d = common difference}
a₁ = 5
a₄ = 5 + d(4 - 1)
-4 = 5 + 3d
-4 - 5 = 3d
3d = -9
d = -3
Therefore;
aₙ = 5 + (-3)(n - 1)
aₙ = -3n + 8
Check: a₁₀ = 5 + (-3)(10 - 1) = 5 - 27 = - 22
