Answer 1

$\mathfrak\red {answer :-} \:$

as given in the figure that all the three lines are parallel to each other

so,

AB||CD||EF

then,

BAO = COA = 25° ...........[ alternate interior angles ]

FEO = COE = 65° ………..[ alternate interior angles ]

so,

AOE = COA + COE

= 25°+ 65°

= 90°

hence, a = 90°
