Please help I don’t understand how to do this!

We can solve this through algebra. So we know two of the angles already which means we can put them in the equation 22+41+3x=90

63+3x=90

Now that we have the equation above, we can solve this through basic algebra.

3x=27

divide both sides by three

x=9 is your answer

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
