Answer:

c=13

Step-by-step explanation:

pythagoras theorem

a^2+b^2=c^2

12^2+5^2=x^2

169=x^2

x=13

This is one of the few combination of triangle you should really memorize.

Answer:

x = 13 in

Step-by-step explanation:

We can tell this is another right angled triangle due to the right angle symbol, meaning to find x we can use Pythagoras theory:

a^2 + b^2 = c^2

As we have both sides, we can calculate x by plugging the values in:

12^2 + 5^2 = x^2

144 + 25 = x^2

169 = x²

Square root both sides to find x:

\sqrt{169} = \sqrt{x^2}

x = 13

Hope this helps!

F the height remains fixed and the side of the base is decreasing by 0.002 meter/yr, what rate is the volume decreasing when the
katrin [286]

The original volume equation looks like this: V = 1/3 * h * (x^2) 
After the side is reduced by 0.002, the new volume would look like V1 = 1/3 * h * (x-0.002) ^ 2 

Then we have: 
V-V1 = 1/3*h*(x^2) - 1/3*h*(x – 0.002) ^2 


= 1/3 * h *(x^2 - (x – 0.002) ^2) 


= 1/3 * h * (0.004x - 0.00004) 


The rate of decreasing is computed by:


(V-V1)/V * 100% = [1/3 * h *(0.004x - 0.00004)] / [1/3 * h * (x ^ 2)] * 100% this would be equal to (0.004x - 0.00004) / (x^2) * 100% 

So replace x by 200, you’ll get:

(0.004(200) - 0.00004) / (200^2) * 100% 

= 0.001999% is the rate of decreasing.
