if one of the angles of a triangle is 130 degree then the angle between the bisectors of the other two angles can be
(a) 65° (b) 50°(c)145°(d)155°


Sagot :

Answer: D) 155

Step-by-step explanation:

let <A, <B,<C are three angles in a triangle.

sum of the three angles in a triangle is 180degree.

<A+<B+<C=180

130+<B+<C=180 since one angle is given

<B+<C =180-130

<B+<C=50

(<B+<C)/2=25----(1)after bisecting sum of the angles

required angle =180-25=155

d is correct answer
