Answer:
x = 60°
y = 75°
z = 45°
Step-by-step explanation:
L and line BC are parallel and AB is the transversal.
So, if LAC = 45°, then z = 45°. ( Internal alternate angles are equal).
If angle A = 75°, then y will also be 75°. ( Internal alternate angles are equal ).
Sum of all the angles of a triangle = 180°.
45° + 75° + x = 180°.
120° + x = 180°.
x = 180° - 120°
x = 60°.
Therefore, x = 60°, y = 75° and z = 45°.
