Question

solve this question with explanation​

Answer 1

as AD Is perpendicular to BC, ADB and ADC are right angles... so in order to find DAC u should use angle sum property... (i.e) 50°+90°+DAC = 180°

so, 140°+ DAC = 180°

DAC= 180-140 = 40°

now to find ABC :-

angle A it is given as 70°

so angle sum property again:

70°+90° + angle ABC= 180°

160° + ABC= 180°

ABC= 180-160

ABC= 20°

hope it helps ❤️❤️
