1 )
z =180 - 112 = 68
y = 360 - 68 - 87 - 103 = 102
2 ) tan Q = 171 / 50 = h / 160 h = 171 (160) /50
=27310/50 = 547.2 cm
3) 5 pint = 2.36588 L
4)
1 kg = 35.274 Oz
so, 133 oz =3.77049 = 3.77 kg
5) area = ( 1/2 * 20 * 15) + ( 36*20 ) + ( 1/2 * pie * r^2) = 150 + 720 + ( 1/2 * 3.14 * 100) = 150+720+157 = 1027 sq. cm
hope i helepd a bit :-)
