Question

If Line DE is parallel to Line FG, and Line KL is perpendicular to Line DE, what is angle GCJ equal to?

Answer 1

∠JAL is 65° because vertical angle to ∠IAK
So angle ∠JAE is 90° - 65° (total angle measure is 90°)
∠JAE is 25°
Therefore ∠ACB is also 25° because alternate interior angles
And ∠JCG is 25° because vertical angles
