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
Whenever you multiply something, you just add it to itself that many times.
ex) 7 × 4 = 7 + 7 + 7 + 7.
Thus n × a = n + n + n + n....a times.
Answer:
13.86
Step-by-step explanation: First- (2.3 * 4/10)
which gives you 27/10
Then (4.16 * 7/1)
Which gives you 11.16/1 (basically 11.16)
Then divide 27/10 which gives you 2.7
add 11.16+2.7
which adds up to 13.86
