Step-by-step explanation:
Answer:
Side CA = 7.8
Step-by-step explanation:
<u>Given:</u>
Acute angled
.

AB = 10
BC = 12
We can use cosine rule here to find the side AC = b
<em>Formula for cosine rule:
</em>

Where
a is the side opposite to 
b is the side opposite to 
c is the side opposite to 

To the nearest tenth <em>b = 7.8</em>
