We subtract them and divide by four to find the common difference d. The intermediate means implies that there are four increments, thus we shall have:
(26-14)=12
hence
12/4=3
thus
d=2 and the missing means are:
26, 23,20,17,14
Answer:

Step-by-step explanation:
Given
Lines x and y
Transversal b

Required
Find 
From the attachment,
and
are vertically opposite.
This means that

Similarly
and
are supplementary angles
So:

Make
the subject



The relationship between
and
is that they are supplementary angles because:

Set up a proportion. Let h = the statue height. h/statue shadow = boy height/boy shadow.
h/25 = 4.5/3.6
Cross multiply and solve for h.
Slope is 2/-1 or -2. Because you go up twice and then you go left once.
