It would be a cube or a square prism.
5x3=15. 15+6=21. The answer would be 3
Angle W:
180 = 90 + 57 + W
180 = 147 + W
W = 33 degrees
Using trigonometry functions to find the side lengths. (SOH CAH TOA)
Side XZ:
cos(57) = XZ / 18
XZ = cos(57) x 18
XZ = 9.8 units
Side XW:
sin(57) = XW / 18
XW = sin(57) x 18
XW = 15.1 units
Hope this helps!! :)
The other leg is 12cm long.
Step-by-step explanation:
Given,
Hypotenuse = c = 15cm
One leg = a = 9cm
Other leg = b
As the triangle is right angled, therefore, using Pythagoras theorem;

Taking square root on both sides;

The other leg is 12cm long.
