ok so its 3 (x's) in total and they = 60? i think u wrote? the drawing goes off the square drawing thing so i cant really tell
anonymous
  • anonymous
the 60 is the degrees of the angles
anonymous
  • anonymous
so all of them = to 60 degrees? as in every single one of them have a value of 60 degrees?
anonymous
  • anonymous
yes, so that means the top angles are 30 + 30. so just use your primary trig ratios since you have 2 right triangles.

so its a 30 60 90 triangle right?
