Question

If one of the angles of a triangle is 130° then the angle between the bisector of the other two angles can be
(a) 50°
(b) 65°
(c) 90°
(d) 155°

Please explain​

Answer 1

Answer:

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
