Question

A 4m ladder leans against a vertical wall. The base of the ladder is 2m from the wall. Calculate the size of angle x.

Answer 1

Answer:

$\huge \underbrace \mathfrak \red{Solution࿐꧂}$

$\large \blue{length \: of \: ladder = 4m}$

$\large\blue{distance \:between \: base \: of}$

$\large\blue{ladder \: and \: wall = 2m}$

$\large\blue{by \: using \: trigonometry}$

$\large \blue{ \cos( \frac{2}{4} ) }$

$\large \blue{ \cos( \frac{1}{2} ) }$

$\large \blue{ \cos(60) }$

$\huge \underbrace \mathfrak \red{Angle\:=cos60°࿐꧂}$

Answer 2

Answer

length of ladder =4cm

base of the ladder=2m

by using trigonometry

cos(2/4)

cos(1/2)

cos(60)
