Question

Angle C is an inscribed angle of circle P. Angle C measures (5x-7) degrees and arc AB measures (2x) degrees. Find x.

Answer 1

This is the concept of geometry, the vale of x can be found as follows;
angle C and arc BC are supplementary angles, therefore:
(5x-7)+2x=180
7x-7=180
7x=187

x=187/7
x=26 5/7
