Answer:
some
Step-by-step explanation:
Angles opposite to the equal sides of an isosceles triangle are equal, so the third angle in this triangle is also 61. Now, you know all the angles in the triangle, you can use the Triangle Sum Theorem, which says that all the angles in a triangle add up to 180.
x + 61 + 61 = 180
x + 122 = 180
x = 58
