It's saying that B is equal to 1, and c is equal to 4. So your gonna square B (multiply it by itself) and add c. Make sense?
We have to find x and x is the hypotenuse. We use this formula:
hyp²=side²+side²
So:
hyp²=side²+side²
hyp²= 12²+9²
hyp²= 225
hyp²= √225
hyp= 15
Therefore, the hypotenuse is 15 and x is 15.
HOPE THIS HELPS!

the value of angle K is 56
Hello!
To find the side length of a square with the diagonal you use the equation

a is side length
d is diagonal length
Put in the values you know

Divide

Multiply
a = 22.6
All the sides are 22.6 feet
Add all the sides
22.6 + 22.6 + 22.6 + 22.6 = 90.4
The answer is 90.4
Hope this helps!
