Question

Geometry Angle of elevation/depression

Answer 1

Answer:

m∠ACB = 49.88°

Step-by-step explanation:

From the figure attached,

Measure of wire AC attached to the top 'C' of the building BC = 340 m

Horizontal distance between the base 'B' of the building and point A = 260 m

Angle of depression = ∠ACB

By applying sine rule in the given triangle,

sin(∠ACB) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

                 = $\frac{AB}{BC}$

                 = $\frac{260}{340}$

m∠ACB = $\text{sin}^{-1}(764706)$

             = 49.88°
