Question

Find XY in the triangle below.

Answer 1

Answer:

XY = 12

Step-by-step explanation:

Cos Ф = $\frac{Adjecent side of Ф}{ Hypotenuse}$

we know that,

                     Ф = 45°, cos 45° = 1/√2

                      Hypotenuse = 12√2

Cos 45° = XY/[12√2]

1/√2 = XY / [12√2]

1 = XY / 12

12 = XY
