Answer:
Step-by-step 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.
