two angles of triangle BCD measure 36 degrees and 46 degrees. what kind of triangle is BCD?

Question

OK I HAVE THE CHOICE FROM:
A. RIGHT TRIANGLE
B. OBTUSE TRIANGLE
C. ACUTE TRIANGLE
D. EQUILATERAL TRIANGLE

SOME ONE PLEASE HELP ME SOON OR I WILL GO CRAZY!!!

Answer 1

wow!!! now please tell me how this gonna help you through life?!!!
righ..
i will give it a go!!!
36+46=82
we have 135 degrees in a triangle so 135-82=53 degrees are left

so it aint A
me finks it aint c
n me also finks it aint d

i will be impressed if im correct here as its been 25 years or so since school but me finks its answer B.

hope this makes sense but took me ages to work out as im a lil stoned!!!

let me know da answer

Answer 2

the sum of the intern angles of a triangle it´s always 180. If you sum 36+46 you obtain 82, so the other angle must measure 98 in order to follow this law.
Now, let´s see what kind of triangle it is.
- A RIGHT TRIANGLE has one angle of 90 degrees.
-An OBTUSE TRIANGLE has one angle of more than 90 degrees
-An ACUTE ANBLE doesn´t have an angle of more than 90 degrees.
-An EQUILATERAL TRIANGLE has all it´s angles of the same measure.

As you see, the triangle BCD is an obtuse triangle, because it has an angle of 98 degrees

Answer 3

Obtuse
36=angle 1 46=Angle 2 180=total degress in a triangle x=missing angle

36+46+x=180
82+x=180
-82 -82
-----------------
x=98

since at least on of the angles is more than 90 degress, its an obtuse triangle. (obtuse means more than 90)

Answer 4

B. obtuse

A triangle is obtuse if one of the angles measures more than 90 degrees.

Answer 5

B) obtuse triangle because third angle is more than 90 degrees.

Answer 6

the answer is b. obtuse triangle

Answer 7

Go with "B"
