exterior angle =sum of its 2 interior opposite angles

x=70+70=140

Answer 2

hi mate

by a given figure

anlge B =70 & angle C = 40

by tringle property

sum of the angle of triangle is equal to 180

so

Angle A+B+C=180

A+70+40=180

A+110=180

A=180-110

A=70

by property of triangle that alternate angle of triangle

A=ACE

SO HENCE

ACE = 70

i hope it helpfull to you...
