Question

Plzzzz solve this problem............

I need help i have exam tomorrow......... Please don't spam.... ​

Answer 1

Step-by-step explanation:

Angle AEC=Angle ACE (Angles opposite to equal angles)

By angle sum property:

40degree+Angle ACE+Angle AEC=180degree

Angle ACE +Angle ACE=180-40

2 Angle ACE=140 degree

Angle ACE=70 degree.

Angle AEC = Angle ACE = 70 degree.

Angle ACF+ Angle ACE+Angle ECB==180 degree(Supplementary angles)

75+70+AngleECB=180-145=35 degree.

Angle AEC = Angle EBC+ECB(By exterior angle property of triangle)

Angle EBC+35=70 degree

Angle EBC= 35 degree.

Hence, Angle EBC = Angle ECB =35 degree.

Therefore, BE =CE as angles opposite to equal angles are equal

Answer 2

Answer:

A+E+C= 180 sum of all angle

AE=AC SO , opposite are equal then opposite angle is equal .

then

E=C

A+2C=180

40+2C=180

2C=140

C=70

E=70

AEC+BEC=180 linear pair

70+BEC=180

BEC=110

ACF+ACE+ECB=180 Linear pair

75+70+ECB=180

ECB=35

E+B+C=180 sum of all angle

110+B+35=180

B=35

opposite angle are equal

then opposite sides are also equal

BE=CE
