Question

please answer Q1 and 2​

Answer 1

Answer:

100+x=180(angle on a line)

x=180-100

x=80

now,x+y+30=180(sum of angles of triangle)

so,80+y+30=180

y=180-110

y=70

z=30(angle between parallel lines)

Answer 2

Step-by-step explanation:

Question 1.

since AC is a line .then.

100° +x = 180°

x = 180- 100

x = 80°

angle B+angle C+angle X = 180°

30 + y + x = 180°

30 + y + 80° = 180°

y = 180° -80° - 30°

y = 70°

therefore , x= 80° & y =70°
