Question

in the figure find b​

Answer 1

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

Answer 2

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°
