In the figure, PQ is the tangent from P to the circle QRS with SR as its diameter. If QPR = \(\theta\)o and RQP = \(\phi\)o, which of the following relationships between \(\theta\)o and \(\phi\)o is correct

\(\theta\)^o + \(\phi\)^o = 90²

\(\phi\)^o = 90² - 2\(\theta\)^o

\(\theta\)^o = \(\phi\)^o

\(\phi\)^o = 2\(\theta\)^o

\(\theta\)^o + 2\(\phi\)^o

स्पष्टीकरण

180 - \(\phi\)o = \(\theta\)o + \(\phi\)o (Sum of opposite interior angle equal to its exterior angle)

180 = 2\(\phi\) + \(\theta\)o
