You can do this by drawing one line through parallel to PQS to meet RQ at T

Now calculate length of RT:-

cos 70 = RT / 70 giving RT = 23.94m

sin 70 = ST/70 giving ST = 65.78 m

draw a line from S perpendicular to PQ to meet PQ at U.

PU = 110 - 65.78 = 44.22 m

tan 50 = SU / 44.22 giving SU = 52.70 m

TQ = SU = 52.70 m

So x = TQ + RT = 52.70 + 23.94 = 76.6 m to 1 dec place.

If Line DE is parallel to Line FG, and Line KL is perpendicular to Line DE, what is angle GCJ equal to?
Svetach [21]
∠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
