Question

Find the value of x? please tell me ​

Answer 1

Let The Other Three Sides Be x

Let The Other Three Sides Be xIn Trapezium ABCD

Let The Other Three Sides Be xIn Trapezium ABCDAngle B & C = 50°

Let The Other Three Sides Be xIn Trapezium ABCDAngle B & C = 50°By Angel Sum Property

Let The Other Three Sides Be xIn Trapezium ABCDAngle B & C = 50°By Angel Sum Property x+x+50°+50°=360°

Let The Other Three Sides Be xIn Trapezium ABCDAngle B & C = 50°By Angel Sum Property x+x+50°+50°=360°2x+100°=360°

Let The Other Three Sides Be xIn Trapezium ABCDAngle B & C = 50°By Angel Sum Property x+x+50°+50°=360°2x+100°=360°x=260/2

Let The Other Three Sides Be xIn Trapezium ABCDAngle B & C = 50°By Angel Sum Property x+x+50°+50°=360°2x+100°=360°x=260/2x=130°

Answer 2

Answer:

total angle sum =360

add the given first two angles

1. 50 +50=100
2. 360-100=260
3. 260/2=130
4. so' x =130
