Step-by-step explanation:
he triangle is isosceles.
The leg-to-hypotenuse ratio is 1:StartRoot 2 EndRoot.
The leg-to-hypotenuse ratio is 1:StartFraction StartRoot 2 EndRoot Over 2 EndRoot. The nonright angles are congruent. The ladder represents the longest length in the triangle.
Hello!
To find the cost of 12 oz:
first oz = $0.37
Every oz after = $0.23
12 - 1 = 11
First oz = $0.37
11 × .23 = 2.53
2.53 + 0.37 = 2.9
A 12 oz package in first class would cost $2.90.
Hope I helped you! :)
PS. Next time please add the answer choices! :)
5 + 27 ÷ 3 / 6 + 1 - Remember PEMDAS, so start by dividing 27 by 3.
5 + 9 / 6 + 1 - Next, add
14 / 7 Lastly, Divide.

Answer:
the altitude of the helicopter is 3925ft
Step-by-step explanation:
we know the angle that is formed between the floor and the distance from the platform to the helicopter (73°)
and we know the distance of the platform (1200 feet)
at the angle we will call it α
and at the distance of 1200 feet we will call it adjacent
we want to know the height that in this case would be the opposite leg to the angle we have
we see that it has (angle, adjacent, opposite)
well to start we have to know the relationship between angles, legas and the hypotenuse
a: adjacent
o: opposite
h: hypotenuse
sin α = o/h
cos α= a/h
tan α = o/a
it's the tangent
tan α = o/a
we replace the values and solve
tan α = o/a
tan 73 = o/1200
3.2708 * 1200 = o
o = 3925
This means that the altitude of the helicopter is 3925ft
