Answer 2

HEY MATE YOUR ANSWER IS HERE...

IN ISOSCELES TRIANGLE OPPOSITE ANGLES ARE EQUAL

LET THE TRIANGLE BE ABC

★ GIVEN ★

VERTEX ANGLE OF TRIANGLE ABC = 50°

TRIANGLE ABC IS ISOSCELES TRIANGLE

★ FIGURE ★

REFFERED TO THE ATTACHMENT

★ TO FIND ★

OPPOSITE ANGLES OF TRIANGLE

( ANGLE ABC AND BCA )

★ PROOF ★

ANGLE ( ABC + BCA + CAB ) = 180°

( ANGLE SUM PROPERTY )

ANGLE ABC = BCA = X

(OPPOSITE ANGLES AN ISOSCELES TRIANGLE )

NOW

ANGLES ( X + X + 50 ) = 180

( VERTEX ANGLE = 50° )

2X = 130

X = 65

HENCE ANGLE

ABC = BCA = 60°

THANKS FOR YOUR QUESTION HOPE THIS HELPS
