I will give a brainlist for the correct answer

Answer:
88 degrees
Step-by-step explanation:
This is an isosceles triangle, meaning that the interior angles next to the base will always be the same.
The interior angles of a triangle will always add up to 180 degrees.
So:
46 + 46 = 92
180 - 92 = 88 degrees
Answer:
88 degrees
Explain:
Calculated based on 2 given angles and 1 given side.
∠C = 180° - A - B = 1.53589 rad = 88°
b = a·sin(B)/sin(A) = 1
c = a·sin(C)/sin(A) = 1.38932
