Answer:
m∠RMS = 20°
Step-by-step explanation:
Find ∠RMS and look at the two values it crosses.
∠RMS crosses through 180 and 160.
Find the difference between the two values to get the measure:
180 - 160 = 20°
So, m∠RMS = 20°
(Its also an acute angle.)
Answer:
Step-by-step explanation:
Start with our equation:
s=2(lw+wh+hl)
Plug in our values for l, w, and h:
s=2(12*9+9*2+2*12)
Simplify:
s=300
