I don't know how to do the last problem, sorry.

You are trying to find the angle at point F. Line AB and DF are parallel.

∠B is the same as∠C, so ∠C = 120°

A straight line is 180°. To find the other angle of the triangle, you do this:

120 + ? = 180

? = 60°

Now that you know 2 of the 3 angles, you can find angle F.

60 + 33 + ∠F = 180

∠F = 87°

Answer:

3764 m

Step-by-step explanation:

Resolvemos usando la función trigonométrica de tangente.

tan θ = Opuesto / Adyacente

θ = Ángulo de depresión = 12 °

Opuesto = 800m

Adyacente = Distancia de la ciudad = x

Cruz multiplicar

bronceado 12 = 800 / x

Cruz multiplicar

bronceado 12 × x = 800

x = 800 / tan 12

x = 3763.7040876 m

Aproximadamente = 3764 m

Which expression is equivalent to<br> (X^1/4 y^16)^1/2?

lawyer [7]

Answer:

$x^{\frac{1}{8} } y^{8}$

Step-by-step explanation:

Given :

$(x^\frac{1}{4} y^{16} )^{1/2}$

Now,

$(x^\frac{1}{4} y^{16} )^{1/2}\\x^{\frac{1}{8} } y^{8}$

Therefore, expression is equivalent to $x^{\frac{1}{8} } y^{8}$
