Answer:
1035.33 feet
Step-by-step explanation:
OBH is a triangle and the sum of the angles of a triangle = 180
∠OBH = 90°
∠OHB = 180 -(49 + 90) = 41°
The law of sines that the ratio of each side of a triangle to the sin of the angle opposite it is the same
Thus
A/sinα = B/sinβ = C/sinγ
where A, B and C are the three sides of the triangle and α, β, γ corresponding respectively to the angles opposite them.
Using the law of sines
Therefore BH which is the height the helicopter is flying at is
≈ 1035.33 feet
Answer:
50%
OR
1/2
Step-by-step explanation:
The box and whisker plot shows the time spent from 4 to 6 hours is Quartile 1 to 3 which makes it 50%.
The first step to solving this problem is Multiplying In(x-1).
Answer:
1624 units²
Step-by-step explanation:
See attachment for the figure
As, ∠EAB = ∠CFD
and ∠ABE = ∠FCD
We can say that by AA congruency, ΔCFD is similar to ΔBAE
Therefore, BA / EB = CF / DC
BA x DC = EB x CF (since EB = CF
)
BA x DC = EB²
28 x 58 = EB² => area of square BCFE
area of square BCFE = 1624 units²
Therefore, the area of square BCFE is 1624 units²
