Answer: BC= 8 units.
Step-by-step explanation:
In the given figure m, we have a Δ ABC in which point D and F are the mid point of sides AB and AC respectively .
We know that the Mid - segment theorem says that a line segment that connects the midpoints of two sides of a triangle is parallel to the third side and it should be equal to one-half of the third side.
Therefore , For the given situation , we have
Since DF = 4 units [Given ]
Then,
Hence, BC= 8 units.
Answer:
Step-by-step explanation:
1). In ΔABC,
For angle A as a reference angle,
Opposite side of ∠A → BC
Adjacent side of ∠A → AC
Hypotenuse → AB
2). By using tangent ratio in ΔYWZ,
tan(72°) =
tan(72°) =
x =
x = 3.899
x ≈ 3.9
3). By using sine rule in ΔKNM,
tan(x°) =
tan(x) =
x =
x = 19.03
x ≈ 19.0°
4). By applying cosine ratio in ΔJKF,
tan(70°) =
tan(70) =
x =
x = 21.838
x ≈ 21.8
Answer:
The constant in the algebraic expression to represent the pattern below is 4.
Step-by-step explanation:
Imortant Tip:
Given the pattern
computing the differences of all the adjacent terms
The difference between all the adjacent terms of the pattern is the same which is
Hence, the given pattern represents the Arithmetic sequence.
Therefore, the constant in the algebraic expression to represent the pattern below is 4.
