if you draw an imaginary perpendicular line across the figure from the vertex which joins the line of 2 cm with the line that is making an angle of X then you can see that this figure is made up of two figures that is a triangle and a rectangle.

now from the angle given i.e X.

perpendicular= 5 cm

base = 14 -2= 12 cm

hypotenuse= ?

we know that,

h² = p²+b²

= 5²+12²=169

h= √169

h= 13

again,

cos X = b/h

= 12/13

13m/1m = ?/100cm I need to have this answer quick, please respond as fast as you can, thank you so much

Answer:

The answer is 13 m/1 m = 1300 cm/100 cm.

Step-by-step explanation:

Given:

13m/1m = ?/100cm.

Now, to find the answer in the place of ? .

13m/1m = ?/100cm.

As, 1(m) metre = 100(cm) centimetre.

So, by multiplying 13 m with 100 we get:

$13 m\times 100 = 1300 cm.$

Thus, 13 m/1 m = 1300 cm/100 cm.

Therefore, the answer is 13 m/1 m = 1300 cm/100 cm.
