Answer:
60
Step-by-step explanation:
alternate angles so angle BCA is 50 too
angles on a straight line at FAB so 180-110= 70
um of angles in a triangle =180 so...
70+50=120
then... 180-120= 60
Hello dear.............
∠BCA = 50° ( vertically opposite angle)
∠BAC = 180-110 = 70° (sum of the two adjacent side is supplementary )
∠B = 180-(50+70) (sum of the three sides of a triangle is 180° or by angle sum property)
∠B = 180-120 = 60°
∠B = 60°
