Question

find the value of all questions ​

Answer 1

Step-by-step explanation:

first angle is x/3

second angle is 2x/3

third angle is x

angle sum property

x/3 + 2x/3 + x = 180

x + 2x + 3x/3 = 180

6x = 540

x = 90

so the angles are

30

60

90

_______________________________________

first angle = x

third angle = 3x/2

second angle = x/2

angle sum property

x/2 + 3x/2 + x = 180

x + 2x + 3x/2 = 180

6x = 360

x = 60

so the angles are

30

90

60
