Answer:
572.4 m
Step-by-step explanation:
Fórmula del ángulo de elevación =
tan θ = Opuesto / Adyacente
θ = 3 °
Opuesto = 30 m
Adyacente =?
Por eso
bronceado 3 = 30 m / x
Multiplicar cruzada
bronceado 3 × x = 30 m
x = 30 m / bronceado 3
x = 572.43410063m
Aproximadamente = 572.4 m
Answer:
Find the area of the trapezoid below.
Step-by-step explanation:
17.83 times 1.1
=19.613
17.83+19.613
=37.443
=37.5 dollars
Picture a right triangle whose hypotenuse is of unknown length. Let's call that length L. The triangle side opposite the 70 degree angle is then 20 feet. I'd suggest you actually draw this triangle.
Then, using the definition of the sine function,
sin 70 deg = opp / hyp = (20 ft) / L. Transforming this equation, L sin 70 deg = 20 ft. Solving for L:
L = (20 ft) / (sin 70 deg) = 21.28 ft
The ladder length must be 21.28 ft.
