Answer:
x = 60°
Step-by-step explanation:
if you look at the isosceles triangle on the left, the obtuse angle must measure 180 - (30 + 30) = 120
that means the left-most angle in the second isosceles triangle must be 180-120, or 60 degrees
therefore, the measure of angle 'x' must be 180 - (60 + 60) = 60
