Question

In a triangle angle A=80 angle B=50 and angle C=?

Answer 1

in any triangle sum of all angle is equal to 180°
so, by this property

<a + <b + <c = 180°

a.t.q

80 + 50 + <c = 180°

130 + <c = 180°

<c = 180°-130°

<c = 50° Answer

Answer 2

ok.....
See ...
As you must know that the sum of all angles of triangle is 180°.

so :- angle1 + angle2 + angle3 = 180°

80° + 50° + x = 180°
( let anlgle3 be ' x')


so the angle3 will be 50°.
