Question

IS 7 7 Solve for a = √[? [] a a = 4 Enter the number that goes beneath the radical symbol 4 Enter​

Answer 1

`a=√(33)`

Explanation:

When we solve for this we should always remember this formula
`a^2+b^2=c^2` and since we already know b and c we can plug that in to find out what a could be but we won't actually solve it.

`a^2+b^2=c^2\\a^2+4^2=7^2\\a^2+16=49\\a^2=33\\√(a^2)=√(33)\\a=√(33)`

So a would equal whatever the square root of 33 is.
