Question

please answer this question in step wise and i make him to brain liest​

Answer 1

Answer:

in the first figure

50+40+x=180 (sum of all the angles of triangle)

x=90 degree

since x+y=180 (linear pair)

so y =90 degree

in ∆BAD

y+z+28=180

so z =62 degree

Answer 2

Step-by-step explanation:

a) first take ∆ ABC

∆ ABC = 40+50+x = 180°

∆ABC = 90+x = 180°

x = 180-90= 90°

so x = 90°

in ∆ ABD

x+y= 180° (linear pair)

∆ABD = 28+90+z = 180°

∆ABD = 118+z = 180°

z = 180-118 = 62°

so z = 62°

(b) ∆ABC

∆ABC = 50+60+x = 180°

∆ABC = 110+x = 180°

x = 180-110 = 70°

x = 70°

in ∆ ABD

x+y = 180° (linear pair)

∆ABD = 40+90+z = 180°

∆ABD = 130+z = 180°

z = 180-130 = 50°

z = 50°
