Answer:

x = 9.2

x =22.0

x = 8.7

Step-by-step explanation:

Required

Find x

(a)

x is calculated using tangent formula

\tan(57) = \frac{x}{6}

Make x the subject

x = 6 * \tan(57)

x = 6 * 1.5399

x = 9.2394

x = 9.2 --- approximated

(b):

x is calculated using cosine formula

\cos(60) = \frac{11}{x}

Make x the subject

x = \frac{11}{\cos(60)}

x = \frac{11}{0.5}

x =22.0

(c):

x is calculated using sine formula

\sin(60) = \frac{x}{10}

Make x the subject

x = 10 * \sin(60)

x = 10 * 0.8660

x = 8.660

x = 8.7 --- approximated

A 13-ft ladder is leaning against a house. The distance from the bottom of the ladder to the house is 7-ft less than the distanc
Olin [163]

Answer:

12 feet

Step-by-step explanation:

As a  ladder is leaning against a house, it forms right angle triangle. And for right angleΔ, we use Pythagoras theorem.i.e

P²+B²= H²

Where,

'P' is perpendicular i.e the distance  from the top of the ladder to the ground

'B' is base i.e be the distance from the bottom of the ladder to the house

'H' is hypotenuse i.e 13

considering 'x' as perpendicular

So, base would be 'x-7'

Applying Pythagoras theorem,

x² + (x-7)²= 13²

x² +x² -14x +49 =169

2x² -14x -120= 0

x² -7x -60=0 ----> solving the quadratic equation

x² + 5x -12x-60=0

x(x+5) -12(x+5)=0

Either : x+5=0 => x=-5

OR: x-12=0 => x=12

We'll choose the positive length.

therefore , The distance from the bottom of the ladder to the house is 12 feet
