So for the two equations: Not sure how hard you want them but....
15+1=16 and 13+ 18=21
For the open equation.

Answer:
2(2x + 1)(3x - 5)
Step-by-step explanation:
<h3>
First Method:</h3>
<u>Using cosine rule</u>:
<h3>
Second Method:</h3>
<u>First find XY using sine rule</u>:
Then use Pythagoras Theorem:
⇒ XY² + YZ² = XZ²
⇒ (6)² + YZ² = 12²
⇒ YZ² = 144 - 36
⇒ YZ = √108
⇒ YZ = 6√3
⇒ YZ = 10.4
