Question

Five of the angles of hexagon are 120'150'92'79'135 find the six angle​

Answer 1

Answer:

144°

Step-by-step explanation:

We know that the sum of angles of hexagon = 720°

given angles = 120 , 150° , 92° , 79° , 135°

Let the required angle be x

So,

120 + 150 + 92 + 79 + 135 + x = 720

576 + x = 720

x = 720 - 576

x = 144°

Sixth angle = 144°

Answer 2

Answer:

sum of all angles of hexagon=(n-2)x180⁰

=(6-2)x180⁰

=4x180=720⁰

sixth angle =720-(120+150+92+79+135)

=720-576

=144
