Question

Help me pls offering good points

Answer 1

Answer: x=12.37 (2 decimal place) and the second box is √153

Step-by-step explanation:

You would have to use pythagoras theorem.

The formula for the short side is x²=c²-b²

The formula with the numbers in it is x²=13²-4²

13²=169

4²=16

x²=169-16

x²=153

To find x on its own you would have to square root 153.

x=12.37 (2 decimal places)

Hope this helps :)
