1.

z + 38° = 180°

(L.P)

z = 142°

y = 32° (alternative angle of angle FCA)

x = 142° (alternative angle of angle z)

2.

x + 65 = 180

(l.p)

x = 180 - 65

x = 115°

y = x (alternative angle of x)

y = 115°

z = y (V.O.A)

z = 115°

Answer:

Explanation:

2) Linear pair: Two angles are called linear when they are adjacent angles and the non common arms form a straight line. They add uo to 180

z + 32 = 180 {linear pair}

z = 180 - 32

z = 148°

When parellel lines are cut by a transversal alternate interior angles are equal.

y = 32° {Alternate interior angles}

x = z {Alternate interior anlges}

x = 148°

3) x +65 = 180 {linear pair}

x = 180 - 65

x = 115°

y = x {Alternate interior angles}

y = 115°

z = y {Verically opposite angles}

z = 115°
