M∠2 = 180 - m∠1 = 180 - 3x [supplementary angles<span>]
</span>In a triangle, the three interior angles always add to 180° ⇒
m∠2 + m∠3 + m∠5 = 180 <span>
180-3x + 2x+20 + 30 = 180
230 - x = 180
x = 230 - 180
x = 50</span>
Mass=5.6
Find this by plugging your values into the density formula and solving for M.
0.05/1 min * 60 min = 0.05 * 60 = 3
<em>Therefore, the unit rate per hour is $3.</em>
