Answer:

35 m

Explanation:

Given :

The distance of the path from the ground to the tree limb = 50 m

The angle between the path of flight of the bird towards the tree limb and the ground = 45 degrees

Therefore we can determine the height above which the bird perched above the ground by using the rules of the trigonometric ratios as;

We know that ,

$\sin 45^\circ =\frac{\text{perpendicular}}{\text{hypothenus}}$

$\sin 45^\circ =\frac{\text{BC}}{\text{AC}}$

$0.7  =\frac{\text{BC}}{\text{50}}$

\text{BC }= 0.7 \times 50

       = 35

Therefore, the bird perched on the tree limb at a height of 35 m.

In gym class you run 22m horizontal then climb a rope vertically for 4.8m. What is the direction angle of your total displacemen
Tanya [424]

The answer is: 12.30 degrees.

The explanation for this exercise is shown below:

1. You can make a right triangle as you can see in the picture attached, where \alpha is the angle asked, the opposite side is 4.8 meters and the adjacent side is 22 meters.

2. Therefore, you can use tan^{-1} to calculate the angle, as following:

tan^{-1}(\alpha)=\frac{opposite}{adjacent}\\tan^{-1}(\alpha)=\frac{4.8}{22}\\\alpha=12.30degrees
