Question

How many unique triangles can be made where one angle measures 98° and another angle is an obtuse angle?

A) 1
B) 2
C) More then 2
D) None

Answer 1

u know what a obtuse angle means ??

Answer 2

obtuse angle are the angle > 90 degree

Answer 3

in one triangle how many angle greater than 90 degree are possible

Answer 4

??

Answer 5

@Kittymeowb

Answer 6

1?

Answer 7

yeah ..and what your Q say??

Answer 8

one angle is 98 and the other obtuse?

Answer 9

so is it possible to have 2 angle greater than 90???

Answer 10

yes?

Answer 11

how ??

Answer 12

sum of all the angle of triangle = 180

Answer 13

98+91+x=180
189+x=180
x=180-189=-9
x=-9degree

Answer 14

it is not possible

Answer 15

o-oh, but how does the angles matter on how many unique triangles i can make?

Answer 16

Obtuse angle means angle which is greater than \(90\).. In a triangle only one angle can be obtuse, so one angle can be greater than 90..

Answer 17

One angle is given to you, that is greater than 90 too, one angle that is given to you is already obtuse..

Answer 18

So, can you make one more obtuse angle in your triangle when you are given one obtuse angle already?

Answer 19

so does that mean the answer would be none? since you said only one can be obtuse?

Answer 20

Exactly...

Answer 21

you can make only one obtuse angle in any triangle and it is given to you already, so further you cannot make any other obtuse angle in the triangle.. So, \(\text{None}\) is the best answer to your question.. :)

Answer 22

\(\text{This is it...}\)

Answer 23

Thank you!

Answer 24

you are welcome dear.. :)
