Answer:
15°
Step-by-step explanation:
AB is parallel to DC and AD is parallel to BC
Therefore, if you put Angle D and Angle C together it must form 180°
If Angle C = 120°, that means Angle D = 60°
Now you subtract 45 from 60 and that gives you 15.
Answer:
5.4
Step-by-step explanation:
To find the distance between each pair of points, we use the distance formula, which is:
d = 
So we have

When we plug in the values into the formula we get:
d = 
d =

Step-by-step explanation:
The question is incomplete as the number line is not attached.
<em>However, the following will guide you through</em>
Given

Required
Determine BC
First, we need to get the fraction of BC using the following

Substitute
for AB

Make BC the subject of formula

Take LCM



This implies that you multiply the length of AC by 2/3 to get BC
<em>Take for instance, AC = 24</em>
<em>BC will be:</em>
<em />
<em />
<em />
<em />
<em />
<em />
<em />
<em>Or if AC = 12</em>
<em>BC will be:</em>
<em />
<em />
<em />
<em />
<em />
<em />
<em />
<em>Or if AC = 36</em>
<em>BC will be:</em>
<em />
<em />
<em />
