Step-by-step explanation:

cos 45° = distance to east / total distance=7,2

distance to east = cos 45° * 7,2 = 5,1 km

Answer:

Step-by-step explanation:

FE=4+4=8

Altitude=3+3=6

area=1/2×FE×6=1/2×8×6=24 sq. units.

area=1/2×

I 1 3|

=1/2[(-3+12)+(12+12)+(12+3)]

=1/2[9+24+15]

=1/2[48]

=24 sq. units

There is no solution to the equation cscx=0.<br> True or False

Svetradugi [14.3K]

Answer:

True

Step-by-step explanation:

First, we need to recognize that

$csc(x)=\frac{1}{sin(x)}$

Now, we can try to solve

$\frac{1}{sin(x)} =0$

Multiply each side by $sin(x)$

$1=0*sin(x)\\\\1=0$

As we end up with an answer that cannot be true, we know that there is no solution.

Another method to solve this would be graphing the function $y=csc(x)$

When graphed, it can be seen that there is an asymptote at x=0 meaning that there is no value for x=0.

How do I solve for question number 6

Natali5045456 [20]

Answer:

$18 + 18\sqrt{3}$

Step-by-step explanation:

The rectangle has been split into two right triangles. The hypotenuse of the triangle (the diagonal) is 18. The angle in the triangle is 30. All right triangles have unique relationships between their sides depending on the angles. This triangle must be a 30 - 60 - 90 triangle and its sides will be a scaled version of $1 - \sqrt{3} -2$ .

The side 2 correspond to the hypotenuse of length 18. 2*9 = 18 and so the scale factor is 9. To find the remaining sides, multiply each side length by 9 from $1 - \sqrt{3} -2$ .

It becomes $9 - 9\sqrt{3}-18$ . So the rectangle is 9 by $9\sqrt{3}$ .

The perimeter of the rectangle is $9 + 9 + 9\sqrt{3} + 9\sqrt{3}=18 + 18\sqrt{3}$
