Mathematics

Part A)

Height = 19.3 feet

Part B)

Distance = 5.2 feet

Step-by-step explanation:

Part A)

Let ladder reaches upto the h height of the wall.

$\therefore \sin \theta =\frac{h}{length\: of\: the \:ladder}$

$\therefore \sin 75\degree =\frac{h}{20}$

$\therefore 0.9659258263 =\frac{h}{20}$

$\therefore 0.9659258263\times 20 = h$

$\therefore 19.3185165 \: ft= h$

$\therefore h = 19.3 \: ft= h$

Part B)

Let the distance from the wall to the base of the ladder be x feet.

$\therefore \cos \theta =\frac{x}{length\: of\: the \:ladder}$

$\therefore \cos 75\degree =\frac{x}{20}$

$\therefore 0.2588190451 =\frac{x}{20}$

$\therefore 0.2588190451\times 20 = x$

$\therefore 5.1763809 \: ft= x$

$\therefore x = 5.2 \: ft$
