Answer:
Step-by-step explanation:
At the point D the angle is 125 for triangle 1. as we know its a straight line...
the angle D of the second triangle + 125 = 180
=> angle D = 180-125 = 55
we know some of all angles in a triangle is 180
Angle D + Angle A + Angle C = 180
55+60+x = 180
=>x = 180-60-55
=>x = 65 deg
The angle x is 65 degree.
Hope this helps :)
