Question

3. Observe the figure and find the length of XY and XZ​

Answer 1

Answer:

in triangle XYZ ,

According to angle ZYX , base = XY , height = ZX

base / hypotenuse = cos theta

XY / 3√2 = cos 45°

XY = 3√2 ( 1/√2)

XY= 3unit

perpendicular/hypotenuse = sin theta

ZX /3√2 = sin 45°

ZX= 3√2(1/√2)

ZX = 3 unit
