Question

In ΔXYZ, ∠X = 100 and XW bisects ∠X and XW ⊥ YZ. Find ∠Y.​

Answer 1

• xw bisects yz, thus angle xwy= 90°
• angle x = 100° degree and xw bisects angle a( given),so angle yxw = 50°
• now in triangle xwy
• angle y+ angle xwy + angle yxw= 180°( angle sum of triangle)
• angle y+ 90°+50°=180°
• angle y = 180°-140°=40° answer
