Oh i done this yes sir u r correct
-4/10+5/10
=5/10-4/10
=1/10
<em>Hi there!</em>

<em>If my logic doesn't fail me here, we have a total of 290 + 145 + 4 = 439 total 6s.</em>
<em>Hope this helped you!</em>
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!! :)
