Upper primary school mathematics question UPQ53
In the figure, GHJ is a straight line and bisecting angle LHK. angle LHK is a right angle. Find angle GHL.
GJ is straight line,
Line GJ is bisecting angle LHK
angle GHL = angle GHK
angle LHK is a right angle
angle GHL = (3600 – 900) ÷ 2 = 2700 ÷ 2 = 1350
