Question

find x,y,z in the following figure​

Answer 1

Answer:

x=50 degree y=130 degree z=20 degree

Answer 2

Answer:

(a)

sum of all angles of triangle =180°

60+70+x=180

130+x=180

x=180-130

x=50°

x+y=180(linear pair)

50+y=180

y=180-50

y=130°

sum of all angles of triangle =180°

30+y+z=180

30+130+z=180

160+z=180

z=180-160

z=20°

(b)

sum of all angles of triangle =180°

55+60+z=180

115+z=180

z=180-115

z=65°

y+z=180(linear pair)

y+65=180

y=180-65

y=115°

sum of all angles of triangle =180°

x+y+40=180

x+115+40=180

x=180-155

x=25°
