Write an expression for total amount of angles in this shape
6x
There are 180° in each triangle. Using this, find the value of x 30
There are 2 numbers in the triangle and 3 x but since there is a 3x and 2x and a normal x so it is x.
Then for the triangle you go 6 divide by 180 and that equals 30 and there is your answer 180.
