Question

in a ∆xyz,if Lx = 90° and Lz =48°,find LY​

Answer 1

Answer:

42°

Step-by-step explanation: Please mark as the brainliest...

According to the angle sum property of a triangle,

In Δxyz, ∠x+∠y+∠z=180°

So, the equation formed will be:

  ∠x+∠y+∠z=180°

⇒90°+∠y+48°=180°

⇒138°+∠y=180°

⇒∠y=(180-138)°

      =42°

∴∠y=42°
