Question

angle a is 40 and angle b is 70 find angle bce

Answer 1

40+70+x= 180
x= 70
hence angle bce of the traingle is70 degrees

Answer 2

Sum of all the angles of a equilateral triangle is 180 degree
Angle A=40 degrees
Angle B=70 degrees
So, By Angle sum property of a triangle
let angle C be x
Angle A+Angle B+x=180 degrees
40 degrees+70 degrees+x=180 degrees
110 degrees+x=180 degrees
x=180 degrees-110 degrees
x=70 degrees Ans.
