Point x is the circumcenter of triangle abc what is the length of xb? 4.2 cm 4.6 cm 4.8 cm 5.3 cm

XB ≈ 5.3 cm

Step-by-step explanation:

From the diagram :

In ΔXNC,

m∠XNC = 90°

Now, m∠XNC + m∠XNB = 180° ( Sum of angles forming a linear pair is supplementary )

⇒ 90° + m∠XNB = 180°

⇒ m∠XNB = 180° - 90°

⇒ m∠XNB = 90°

Now, in right angled ΔXNB Applying Pythagoras theorem , We have

XB² = NB² + XN²

⇒ XB² = 4.2² + 3.2²

⇒ XB² = 27.88

⇒ XB = 5.28 cm

⇒ XB ≈ 5.3 cm

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
