Question

angle b=72 angle c=68 find the angle a?​

Answer 1

Answer:

i think this is a triangle because it's have only 3angles

given

angle b=72, angle c=68,

sum of triangle=180°

let a angle be 'x'

72+68+x=180°

140+x=180

x=40

therefore other angle is 40°

here is ur answer

Answer 2

Answer: 40°

Step-by-step explanation:

Note :

The sum of interior angles of a triangle = 180 °

angle a = 72 ° , angle b = 68° (given)

Angle a + b + c = 180°

So, angle c = 180° - (angle a + angle b)

angle c = 180° - ( 72° + 68°)

angle c = 180° - 140° = 40°
