Question

Find the unknown value of x, y and z​

Answer 1

Answer:

x=80°

y=60°

z=40°

Step-by-step explanation:

x + <D + <E = 180° (angle sum property)

x + 100° = 180°

x = 80°

y = <D = 60° (corresponding angles of transversal intersecting two parallel lines)

<A + <B + <C = 180° (angle sum property)

80° + 60° + z = 180°

140° + z = 180°

z = 40°
