Step-by-step explanation:
the x distance from A to B is 3 (from -1 to 2), and the y distance is 15 (from -4 to 11).
the x distance from C to D is also 3 (from 1 to 4), but the y distance is 9 (from 1 to 10).
so, the slopes are different
AB : 15/3 = 5
CD : 9/3 = 3
and the lines are therefore not parallel.
perpendicular slopes are simply inverting y and x in the ratio and flip the sign (from - to + and vice versa). but that is not the case here either (just to start - both slopes are positive).
so, the 2 lines are "neither".
Answer:
h = 27.3
Step-by-step explanation:
A = bh
h = A/b
h = 210.21 / 7.7
h = 27.3
Answer:
Step-by-step explanation:
<u>Given</u>
<u>Solving for x</u>
- 4(1 - x) + 3x = -2(x+1)
- 4 - 4x + 3x = -2x - 2
- 4 - x = -2x - 2
- - x + 2x = - 2 - 4
- x = - 6
The height of the tree is 9 meters
<h3>What is angle of elevation?</h3>
This is the angle the line of sight makes with the horizontal.
Analysis:
The line of sight , the shadow length and height of tree form right angled triangle.
Let the height of tree be h
so that, tan 24 = h/20
h = 20 tan 24
h = 20(0.445) = 8.9m = 9m
In conclusion, the height of the tree is 9m.
