Answer:
Option (2) and Option (4)
Step-by-step explanation:
From the picture attached,
Length of ladder AC = 20 feet
Height of the highest point of the ladder from ground AB = 16 ft
By Pythagoras theorem,
AC² = BC² + AB²
BC² = AC² - AB²
BC =
=
=
= 12
Now, Sinθ =
=
Cosθ =
=
tanθ =
=
Therefore, Option (2) and Option (4) are the correct options.
The correct answer is B.
0.5(4x + 12)
2x + 6
