Answer:
132 feet
Step-by-step explanation:
Given that Alejandro is standing at a distance of 140 feet from the base of the tree and his eyes are 6 feet above the ground.
Let AB is the height of the tree and point E is the location of his eyes which is 6 feet above from C on the ground as shown in the figure.
The distance between points A and C, AC=140 feet.
Drawing a horizontal line from point E which meets AB at point D as shown.
As ACED forms a rectangle, so
AC=DE=140 feet ...(i)
CE=AD= 6 feet ...(ii)
The height of the tree, AB=AD+DB
By using equation (ii), AB=6+DB ...(iii)
Now, given that the on watching the top of the tree, the reading on the clinometer is 42 degrees.
So,
In triangle DEB,
[from (i)]
feet
From equation (iii) the height of the tree is
AB=6+126=132 feet.
Hence, the height of the tree is 132 feet.
To find the answer, move the decimal point over until you reach the final number. Move it to the right of that, and then count how many places you had to move over and write that as the exponent to 10. So the answer is A because you moved the decimal point 21640. <- here over 4 places, then you lose the zero.
Answer:
Ratios equivalent to 2:3 include:
4:6
6:9
8:12
10:15
12:18
14:21
All of the above ratios are equal to 2:3 when multiplied. To get the above ratios, multiply 2:3 by the same number to get the resulting ratio. The first ratio answer is 4:6. To get this we multiply both values in 2:3 by 2 to get 4:6.
2:3
2*2= 4
3*2= 6
= 4:6
The second ratio answer was 6:9. To get this we multiply both values in 2:3 by 3 to get 6:9.
2:3
2*3= 6
3*3= 9
= 6:9
