Question

Angle ACD is an exterior angle abc the measuer of angle a and angle bare equal if measure angle acd=140 ° find the measures of the angle a and angle b​

Answer 1

Answer:

As a and b are equal so let a and b be x

angle sum property

140+x+x=360

140+2x=360

360-140=2x

220=2x

220/2=x

110=x

measure of a and b is 110

let's check

110+110+140=360

yep correct
