Given:
Consider In Right Angle Triangle ABC
∠B = 90°
∠C = ∠A = 45°
AB = y
BC = x = adjacent side
AC = 8 = hypotenuse
To Find:
x = ?
y = ?
Solution:
In Right Angle Triangle ABC by Cosine Identity we have
substituting the above given values we get
As The triangle is 45 - 45 - 90
It is an Isosceles Right triangle
..... Isosceles Triangle property
Therefore,
