Question

how to find two angles of a triangle when one angle ?is given​

Answer 1

Answer:

if it is a isosceles triangle we can take the two base angle as x and then take the angle sum property for example if one angle is 30 degree

then

30 + X + x =180

30+2x=180

2x=180-30=150

x=150/2

x=75

then both the angles is 75 degree
