Answer:
50°, 65° and 65°
Step-by-step explanation:
since, ABC is an isocelles triangle.
Hence, AB=AC
now angles opposite to equal sides are also equal
therefore,
<ABC = <ACB = x (let)
now, by angle sum property of triangle
<BAC + <ABC + <ACB =180
50 + x + x =180
2x = 130
x=65
therefore angles of triangle are
50°, 65° and 65°
