Question

find the ans with steps and formula​

Answer 1

Answer:

3) y=100° (opposite angles to B )

x= 180°-100°=80° ( adjacent angles )

z=80°(opposite angle to x)

4)y=80°(opposite angle to B)

x=180°-80°=100°( adjacent angles)

z=( to find z we have to first find angle C)

C=x =100°( opposite angle)

z+c=180°( Linear pair)

z=180°-C

z=180°-100°=80°

or

z=AngleB= 80°( same side of transversal)

Answer 2

Answer:

STEPS ARE IN ATTACHMENT

Step-by-step explanation:

(3)

$x = 80 \: y = 80 \: z = 100$

(4)

$x = 100 \: y = 80 \: z = 80$
