Answer 1

Answer:

as there is no angles given to the diagram and the total diagram is to be measured into 180=2×right angles

so in each trangle there are three angles and there are five triangles to be found so five triangles×3angles=5×3=15

so ,180/15=12°

each angle measures 12°

this sum doesn't have any formula

hope this helps u dude
