Answer:
x =~ 31.2
y =~ 18
z =~ 9
Explanation:
cos 30º = 27 / x
0.8660 = 27 / x
x = 27 / 0.8660
x =~ 31.18
w = height (smaller trinagle w, y, z)
tg 30º = w / 27
0.5774 = w / 27
w = 27 * 0.5774
w = 15.5898
tg 30º = z / 15.5898
0.5774 = z / 15.5898
z = 0.5774 * 15.5898
z = 9.00155052
cos 30º = 15.5898 / y
0.8660 = 15.5898 / y
y = 15.5898 / 0.8660
y =~ 18
