25 metres tall.
Explanation:
The heights of the trees are directly proportional to the length of their shadows because at the same time of day, the sun will be at the same angle in the sky.
The trees and their shadows form 2 similar triangles:
Write as a proportion:
<span><span>heightshadow</span> <span>x20</span>=<span>1512</span></span>
<span>12x=20×15</span>
<span>x=<span><span>20×15</span>12</span></span>
<span>x=25</span> metres tall.
As check: find the constant for each tree:
<span><span>1512</span>=1.25 and <span>2520</span>=<span>1.25</span></span>

Answer: C
Step-by-step explanation:
Answer:
The correct answer is third option
1/√3
Step-by-step explanation:
From the figure we can see a right angled triangle ABC.
Right angled at C.
AB = 10
AC = 5
BC = 5√3
<u>Points to remember</u>
Tan θ = Opposite side/Adjacent side
<u>To find the value of tan(B)</u>
Tan B = Opposite side/Adjacent side
= AC/BC
= 5/5√3
= 1/√3
Therefore the value of tan(B) = 1/√3
