Question

How do you find the measure of a angle?

Answer 1

use a protractor:):)

Answer 2

I dont have one. Is that the only way?

Answer 3

Protractor is a 'D' like scale thing used to measure the angle..seen it anywhere??

Answer 4

didnt u ever see one melissa??

Answer 5

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

Answer 6

My assignment is to find find the measure for angles 1, 2, 3, 4, and 5.In the figure below

Answer 7

ohh:( wheres the figure???

Answer 8

its below you lol

Answer 9

Sorry, I will send attach in one sec:)

Answer 10

i think I became a pro at reimann sums last night...

Answer 11

You can also draw a right triangle, measure the sides and the angle can be derived from sin-1(x/y)

Answer 12

what do you know about right triangles? or triangles in general.... their angles all add up to what number?

Answer 13

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)

Answer 14

so 90+65+F=180 and now u can find out the angle F which is nothing but 25degrees

Answer 15

and angle E is 45+25+E=180
=> 110 degrees

Answer 16

ok, so is <1=65

Answer 17

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

Answer 18

no no angle1=F=25degree

Answer 19

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

Answer 20

1=25deg
2=115
4=65
3=65
5=50 degrees

Answer 21

You 're welcome Melissa, plz do get back if u still have doubts:):)

Answer 22

hmmm not bad...

Answer 23

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

Answer 24

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

Answer 25

Thinker you rock!!!

Answer 26

ok, Thanks Amistre64. You got jokes but I have tears... Have a nice day

Answer 27

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

Answer 28

Tell me why angle 4 does not equal angle 5 as they are vertical angles/

Answer 29

I would double check believe Angle 4 = Angle 5 =50 degrees.
Angle 1 = 25 dcegrees, angle 2 = 115 Degrees, angle 3 = 65 degrees.

Answer 30

Will someone else wade in on this and verify?

Answer 31

Radar your answers appear to be correctly deduced.

Answer 32

I was hoping for a correct dedoosing lol

Answer 33

Thanks mycoalson

Answer 34

i guess the only way is to use a use a protractor:):) if not i have no clue at all.lol

Answer 35

That would work if the angles were drawn accurately!

Answer 36

@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.
