Need with number 7!

Mathematics
1 answer:

Answer: 6

SOLUTION

∵segment\frac{}{AB}is tangent to the circle at point C.

∴∠MCA=∠MCB=90°

Suppose \frac{}{MC} =x

From the Pythagorean theorem

MA²=9²+x²

MB²=4²+x²

∴MA²+MB²=AB²

i.e. x^{2} +9^{2} +4^{2} +x^{2} =(9+4)^{2} \\2x^{2} +97=169\\2x^{2} =72\\x^{2} =36\\x=6

We conclude that x=6=\frac{}{MC}
