In the diagram shown below AB =BC=5.6cm, DC=9.0cm, Angle ABC=90 and angle ACD=34 A. Calculate the length of AC_
B. Calculate the area of the triangle ACD._
C. Calculate the area of quadrilateral ABCD._

the correct answer is 828.07

x = -2

y = 848

step-by-step explanation:

plug in the numbers

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

the first option i believe
