Question

Please koi answer kardo na yaar​

Answer 1

x + 75 + 45 = 180° (linear pair)

x = 180 - 120 = 60°

____________________________

y = 75° (Alternative angle)

____________________________

z = 45 ° (Alternative angel)

Answer 2

Answer:

75°+x°+45°=180(linear pair)

x°=180-120

x=60°

l parallel to bc

Sine

B=75°(alternatively opposite angles)

x+y+z=180

60+75+z=180

135°+z=180

z=180-135

z=45

also

since L parallel to bc

z=45(alternatively opposite angles)
