Question

If segment AC and segment BCare tangent to circle o, find thevalue of x.A0x50°CBx = [?]°=

Answer 1

ANSWER :

130 degrees

EXPLANATION :

Note that the figure formed by two segments AC and BC is a quadrilateral.

Since the two angles at the point of tangency are 90 degres, the two remaining angles will be supplementary or have a sum of 180 degrees.

That will be :

$\begin{gathered} x+50=180 \\ x=180-50 \\ x=130 \end{gathered}$
