Answer 1

Answer:

B. 5 m

Step-by-step explanation:

Here, let the distance between the foot of the pole and foot of the wall be x.

Now, as we know that,

⇒ cos(Ф) = $\frac{Base}{Hypotenuse}$ = $\frac{x}{10 m}$

⇒ cos (60°)= $\frac{x}{10}$

⇒  $\frac{1}{2}$=$\frac{x}{10}$                                                                             [ Since cos (60°) =$\frac{1}{2}$ ]

⇒ x=10/2 m

⇒ x= 5m

Answer 2

Answer:

Your answer is...

tanθ = p/b

tan60° = 10/b

√3/1 = 10/b

√3b = 10

b = 10/√3

so, b = 17.32m

Hence, Your correct answer is 17.32m....
