6w-y=2z
6w=2z+y
w=(2z+y):6
w=(z:3)+(y:6)
Answer:
box is there so I'll put the money in the post
Tan 18 = opposite side/adjacent side
0.3249 = 4/adjacent side
and adjacent side = 4/0.3249 = 12.31
Now let's apply Pythagoras to find x
4² + 12.31² = x²
16 + 151.55 = x² and x² = 167.55
Then x = √167.55 and x = 12.94 ≈ 13
