Answer:

$\frac{8h}{\sqrt{2}} + 16h$

Step-by-step explanation:

First we need to compute the side length as a function of h

So x be the side length of the right isosceles triangle, in Pythagorean formula we have

$x^2 + x^2 = h^2$

$2x^2 = h^2$

$x = \frac{h}{\sqrt{2}}$

The cost for the legs is

$C_l = 4*2x = \frac{8h}{\sqrt{2}}$

The cost for the hypotenuse is

$C_h = 16h$

So the total cost in term of h is

$C = C_l + C_h = \frac{8h}{\sqrt{2}} + 16h$

N is greater than it equal to 3

So you put a shaded in for a three and draw a line to the right

I think :)

Scrat [10]

Answer:

x=36.08

Step-by-step explanation:

Given: From the given triangle DEF, ∠E= $90^{0}$

DF=55

and DE= x

To find the value of x

According to trigonometry rule,

$\frac{x}{55} =cos49^{0} \\x=55(cos 49^{0} )\\x=55(0.656)\\x=36.08$

Therefore, the value of x will be 36.08
