Question

Please help me solve the equation in the picture I have to get it done soon!​

Answer 1

Answer:

square root of 5 squared minus 4 squared

Step-by-step explanation:

a^2 + b^2 = c^2

c^2 - b^2 = a^2

5^2 - 4^2 = a^2

25 - 16 = a^2

9          = a^2

√

√9=a

a=3

or

a=  √25-16

a= √9

a=3

Hope this helps!
