use a protractor:):)

  • anonymous
I dont have one. Is that the only way?
anonymous
  • anonymous
Protractor is a 'D' like scale thing used to measure the angle..seen it anywhere??

didnt u ever see one melissa??

Yes, I just don't have one at home with me, and I'm trying to complete my work assignment.

My assignment is to find find the measure for angles 1, 2, 3, 4, and 5.In the figure below
anonymous
  • anonymous
ohh:( wheres the figure???

You can also draw a right triangle, measure the sides and the angle can be derived from sin-1(x/y)
amistre64
  • amistre64
what do you know about right triangles? or triangles in general.... their angles all add up to what number?
anonymous
  • anonymous
okay, let me tell u one thing, the sum of angles inside a triangle=180 degrees... and the angle 'j' is a 90 degree means a verical(right angle)
anonymous
  • anonymous
so 90+65+F=180 and now u can find out the angle F which is nothing but 25degrees
anonymous
  • anonymous
and angle E is 45+25+E=180 => 110 degrees
anonymous
  • anonymous
ok, so is <1=65
anonymous
  • anonymous
and u see that line DE is parallel to the ray passing through j, so diagonally opposite angles are same i.e. angle DJH=65degrees
anonymous
  • anonymous
no no angle1=F=25degree
anonymous
  • anonymous
Ok, I will study your previous notes and hopefully understand angles. Thanks so much for your help. Geometry is new to me and i'm totally confused
anonymous
  • anonymous
1=25deg 2=115 4=65 3=65 5=50 degrees
anonymous
  • anonymous
You 're welcome Melissa, plz do get back if u still have doubts:):)

hmmm not bad...

WOW, Thanks I think I actually understand now:)... Weird; because math is soooooo hard for me. Hopefully I pass the test Monday

trust me this aint math.... its pictures lol

Thinker you rock!!!
anonymous
  • anonymous
ok, Thanks Amistre64. You got jokes but I have tears... Have a nice day

The answer to this question really depends on what level of math you are trying to use as well as what information is given.

Tell me why angle 4 does not equal angle 5 as they are vertical angles/
radar
  • radar
I would double check believe Angle 4 = Angle 5 =50 degrees. Angle 1 = 25 dcegrees, angle 2 = 115 Degrees, angle 3 = 65 degrees.
radar
  • radar
Will someone else wade in on this and verify?
anonymous
  • anonymous
Radar your answers appear to be correctly deduced.
radar
  • radar
I was hoping for a correct dedoosing lol
radar
  • radar
Thanks mycoalson
anonymous
  • anonymous
i guess the only way is to use a use a protractor:):) if not i have no clue at all.lol
radar
  • radar
That would work if the angles were drawn accurately!
anonymous

@Radar: I've always had a problem with dooses myself. As to measuring angles, again, depends on your givens and your level of math. In the included diagram, all the givens were angles geometrical logic could be used.
