Question 8 (2+2+2 = 6 marks) The diagram shows a pentagon ABCDE.
DC is parallel to AB.
The size of an exterior angle at A is 67°
The size of an exterior angle at B is 112°
The size of an exterior angle at C is tº
The size of an exterior angle at D is 74°
The size of an exterior angle at E is yº
(a) (i) Work out the value of x.
(ii) Work out the value of y.
(b) Work out the sum of the interior angles of the pentagon ABCDE.​

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

answer: the first graph

step-by-step explanation:

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
