Question

find the measure of x y z in the figure where is/ 11 BC​

Answer 1

Answer:

x=60°     y= 75°      z=45°

Step-by-step explanation:

l is parallel to BC

Therefore,

y = 75° (Alternate angles)

z = 45° (Alternate angles)

In triangle ABC,

x + y + z = 180 ° (Angle Sum property)

x + 75° + 45° = 180°

x + 120° = 180°

x = 180° - 120°

x = 60°
