Whats the area of the lawn in this shape

Licemer1 [7]

Answer:

208 ft

Step-by-step explanation:

in order to do this we need to find the area of the retangle:

(l x w) 14x20= 280ft

then the area of the rectangle:

a^2 + b^2 = c^2 ( hypotenus lenght )

c= 8.5

now we can plug in to find the area of the triangle, which is 12 (11.99)

then the area of the trapezium= 60

finally we can find the answer

280 - (60+12)= 208 ft :)

One angle be x

other is 2x-6

ATQ

$\\ \sf\longmapsto x+2x-6=90$

$\\ \sf\longmapsto 3x-6=90$

$\\ \sf\longmapsto 3x=96$

$\\ \sf\longmapsto x=32$

$\\ \sf\longmapsto 2x-6=2(32)-6=58°$

Given sec(theta)= 5... find cot(90-theta)

Mumz [18]

$\sec(\theta)=\frac{1}{\cos(\theta)}
\\
\\\cos(\theta)=\frac{1}{\sec(\theta)}=\frac{1}{5}
\\
\\ \sin^2\theta+\cos^2\theta=1
\\
\\\sin\theta= \sqrt{1-\cos^2\theta}= \sqrt{1-( \frac{1}{5})^2 } = \sqrt{1- \frac{1}{25} } = \sqrt{ \frac{25}{25} -\frac{1}{25} }=\frac { \sqrt{24}}{5} 
\\
\\ \cot(90^o-\theta)=\tan{\theta}= \frac{\sin\theta}{\cos\theta} = \frac{\frac { \sqrt{24}}{5} }{ \frac{1}{5} } = \sqrt{24} = \sqrt{4\times6}=2 \sqrt{6} 
\\
