Answer:

Yes, all three of them are proportional

Step-by-step explanation:

First, let's simplify them all the way:

10/45 = 2/9

20/90 = 2/9

6/27 = 2/9

All three of these ratios simplified down to their simplest form are 2/9, meaning that they are all proportional.

Answer:

The sin A expressed in ratio form is $\frac{\sqrt{6} }{4}$

Step-by-step explanation:

From the given right angled triangle diagram, sin A is calculated as follows;

$sin \ A = \frac{Opp}{hypo} \\\\sin \ A = \frac{2\sqrt{6} }{8} \\\\sin \ A = \frac{\sqrt{6} }{4}$

Therefore, the sin A expressed in ratio form is $\frac{\sqrt{6} }{4}$

Answer:

$90m^2 and 144 m^2$

Step-by-step explanation:

Given :

Length of the rectangle (l)=15m

Width of the rectangle (w)= 6 m

Area of the rectangle can be calculated as :

$A=l*w\\A=(15)(6)\\A=90 m^2$

Now,

Side of square (s)=12 m

Area of the square can be find:

$A=s^2\\A=12^2\\A=144 m^2$
