\begin{gathered}so \: here \: \\ secA + tanA =x \\ ie \: tan \: A = x - sec \: A\end{gathered}
sohere
secA+tanA=x
ietanA=x−secA
\begin{gathered}so \: now \: using \\ 1 + tan ^{2} A = sec {}^{2} A \\ 1 + (x - sec \: A) {}^{2} = sec {}^{2} A \\ 1 + x {}^{2} + sec {}^{2} A - 2sec \: A.x = sec {}^{2} A \\ 1 + x {}^{2} - 2sec \: A.x = 0 \\ ie \: 1 + x {}^{2} = 2secA.x \\ sec \: A = 1 + x {}^{2} /2x \\ \\ \end{gathered}
sonowusing
1+tan
2
A=sec
2
A
1+(x−secA)
2
=sec

A
1+x
2
+sec

A−2secA.x=sec
2
A
1+x

−2secA.x=0
ie1+x

=2secA.x
secA=1+x

/2x
\begin{gathered}thus \: value \: of \: sec \: A \: (in \: terms \: of \: x) \: is \: 1 + x {}^{2} /2x \\ \end{gathered}

hey here is your answer

refer the reference diagram uploaded above
Step-by-step explanation:
so basically Corresponding angles are the angles that are formed when two parallel lines are intersected by the transversal.
So corresponding angles are only and only equal when two lines are parallel
Conditions for two lines to be parallel:
1.When alternate angles are equal
2.When corresponding angles are equal
3.When sum of interior angles is supplementary
