Answer:

Perimeter is 126cm and area is 972 $cm^2$

Step-by-step explanation:

Scale factor means you multiply the dimensions by the factor. In this case 4.5

The width 6cm becomes 27cm. The length 8cm becomes 36cm.

Perimeter = 2*L + 2*W, L is length and W is width.

$P=27*2cm+36*2cm\\P=54cm+72cm\\P=126cm$

Area = L*W

$A=27cm*36cm\\A=972cm^2$

#1
$sin(51^o)= \frac{y}{12} \ \ \to \ \ y=12*sin(51^o)=12* 0.7771 \approx 9.33$

#2
$\theta=arccos( \frac{5^2+13^2-12^2}{2*5*13}) = arccos( \frac{25+169-144}{130})=arccos( \frac{50 }{130})= \\ \\ arccos(0.3846) \approx67.4^o$

#3
$tan(13^o)= \frac{x}{24} \ \ \to \ \ x=24*tan(13^o)=24* 0.2309 \approx 5.54$

#4
$sin(20^o)= \frac{10}{x} \ \ \to \ \ x= \frac{10}{sin(20^o)} = \frac{10}{0.342} \approx 29.24$

slava [35]

Answer:

Graph in attachment and Solution set is x € (⅕ ,-∞)

Step-by-step explanation:

We need to graph the solution of a inequality . For graph refer to the attachment . Let's solve out and find the solution set of inequality .

=> 5/3x < 10

=> 5 < 10 * 3x

=> 5 < 30 x

=> 5 /30 < x

=> x > 1/5

Basically we need to plot here x > 1/5 . The solution set will be , x € ( 1/5 , -∞ )
