Answer:
X=0.8 or x=4/5
Step-by-step explanation:
X + y = 47
x - y = 3
--------------add
2x = 50
x = 50/2
x = 25
x + y = 47
25 + y = 47
y = 47 - 25
y = 22
ur numbers are 22 and 25
Answer:
45°
Step-by-step explanation:
The diagram for this question has been attached to this response. Please check.
<em>The angle of elevation is the angle between a horizontal line from a viewer and the line of sight to an object being viewed which is above the horizontal line.</em>
From the diagram;
θ is the angle of elevation
x = height of the tree
y = length of the shadow of the tree = x
Therefore,
tanθ =
[Remember that y = x? Then substitute into the equation]
tanθ = ![\frac{x}{x}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7Bx%7D)
tanθ = 1
θ = tan⁻¹(1)
θ = 45°
Therefore, the angle of elevation is 45°
