Answer:

sqrt 11

Step-by-step explanation:

Pythagorean theorem again. a^2+b^2=c^2. The hypotenuse is the c value. One of the legs is either a or b, doesn't matter which. So you can make the equation 5^2+b^2=6^2. 25+b^2=36. Subtract 25 from each side to isolate the b variable. You're left with b^2=11. Now you take the square root of each side to get b. This makes b= sqrt 11.

Answer:

b=4

Step-by-step explanation:

a^2 + b^2 = c^2

substitute:

3^2+b^2=5^2

9+b^2=25

25-9=b^2

16=b^2

the square root of 16=4

b=4

check:

4 times 4 = 16
