Step-by-step explanation:
7 ) 8)
In Δ ABC In Δ XYZ
∠ C = 45° ∠ X = 60°
∠ A = 90° ∠ Y = 90°
To Find :
x = ?
y = ?
Solution:
We Know
In Δ ABC
∠ C = 45°
∠ A = 90°
∴ ∠ B = 45° ......Angle sum property of a triangle i.e 180°
∴ Δ ABC is an Isosceles Triangle
∴ AC = AB = x =
Now appplying Trignometry identity we get
Now In Δ XYZ
∠ X = 60°
∠ Y = 90°
∴∠ Z = 30° . .....Angle sum property of a triangle i.e 180°
Now appplying Trignometry identity we get
Now,
