Question

This is with tangents I have already figured out one portion of the problem please help

Answer 1

-5

Explanation:

when x is squared it will always be positive so x can be negative or positive

Answer 2

Explanation:

Tangents drawn to the circumference of a circle are equal.

x^2 + 8 = 33 Subtract 8 from both sides

x^2+8-8 = 33 - 8 Combine

x^2 = 25 Take the square root of both sides.

√x^2 = √25

x = ± 5

So x = 5.

x can also be - 5. The minus goes away when you calculate x^2

because x is squared, you can get two answers, but be very careful when doing geometry questions that the minus number is used in such a way that only a positive value will be left.
