Question

find x .pls pls I beg you pls​

Answer 1

Answer:

Value of x = 70°

Step-by-step explanation:

We Have :-

∠BCD = 30°

∠BAM = 70°

∠DEN = 60°

To Find :-

x

Solution :-

∠BAM + ∠BAE = 180° ( Linear Pair )

∠BAE = 110°

∠DEN + ∠DEA = 180° ( Linear Pair )

∠DEA = 120°

In a Pentagon

Sum of all angles of a Pentagon = 540°

∠BCD + ∠CDE + ∠DEA + ∠EAB + ∠ABC = 540°

30° + 2x + 120° + 110° + 2x = 540°

4x = 280°

x = 70°

Value of x = 70°

Answer 2

Answer:

x=70°

Step-by-step explanation:

Angle BAM+AngleBAE=180°(Linear pair)

70+angleBAE=180°

Angle BAE=180-70

Angle BAE=110°

From similar method we will find the value of angle DEA which will be 120°

AngleBCD+AngleCDE+AngleDEA+ AngleBAE+AngleABC=360 (Angle Sum Property)

30+2x+120+110+2x=540

260+4x=540

4x=540-260

4x=280

x=280/4

x=70°
