Please find X for me this is Pythagorean theorem

x = 6 *

Step-by-step explanation:

I assume x is the diagonal. length

if so here it goes:

the base length is  18

the height of the triangle should be ... 13 - 7 = 6

so hypotenuse = root ( 18^2 + 6^2) =  root(324 + 36) = root(360) = 6root(10)

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
