Question

pls answer this qn.
also pls say how mark brainliest also

Answer 1

Answer: x = 40° , y = 130° , z = 130°

Step-by-step explanation:

since they all are parallel lines, angle ACD = angle DCE = angle CEF = 90°

so, x + 50° = 90°

= x = 40°

now angle BEF and angle y are co interior

so, y + 50° = 180°

= y = 130°

now angle y and angle z are corresponding

so, angle z = angle y = 130°

Answer 2

Hey friend, Here is your answer-
Angle BEF = Angle DEF........(B-D-E are collinear points )
Angle DEF + angle y = 180°........(Interior Angles property)
50° + y = 180
Angle y = 130°

Angle y = Angle z...........(corresponding Angles theorem)
Angle z = 130°

In triangle ABE ,
Angle BEF = Angle ABE........(Alternate Angles)
Angle ABE = 50°
Angle BAE = 90°............. (given)

Angle ABE + angle BAE + angle AEB = 180°.......(Sum of angles of triangle is 180°)
50°+ 90° + angle ABE = 180°
Angle ABE = 180° -140°
Angle ABE = x = 40°

x = 40° , y = 130° , z = 130°

Hope it will help you friend.
