Since there are three triangles, therefore the total sum of angles = No. of triangles × 180 = 3 × 180 = 540 and as we put some logic in the problem we observe that we don't need to find the three angles from each triangle and that all these three angles lie on a straight line so we will subtract the sum of the three angles i.e. 180 from the total sum of the angles.Therefore, 540 - 180 = 360 , which is the answer.

each angle will be equals to 60' so no. of sides * 60 or 6 * 60 = 360

You cannot say that each triangle is an equilateral triangle .

Using by the properties of parallel lines, we can decide the answer.

There are 3 triangles which mean that the total measure of 3 triangle are 180*3=540. The question was asked to find out 6 angles so just subtract 540-180=360 because measure of 3 angles of triangle is180

There is no information to suggest that any equilateral triangles.

it is an Equilateral Triangle so measure of all angle is 60.

I worked on the basis that they were all equilateral triangles therefore each angle is 60deg. 60*(the amount of angles needed: 6)=360

add the combined internal angles for all 3 (540) and take away the sum of the angles that are missing (180). also, simply by looking you can kind of tell this is the case
