D+100+40=180
d=180-100-40=40 (sum of all angles)
e= 100+40= 140 (exterior angle)
180-140=40
C+50+40=180
C=180-50-40= 90 (right angle)
A=50
B=180-90-50= 40
Answer:
.4
Step-by-step explanation:
Its just a matter of subbing ur numbers into the formula given
1. d = rt
when r = 144 and t = 18
now we sub
d = 144 * 18
d = 2592 <==
2. d = rt
when r = 56 and t = 3.5
sub
d = 56 * 3.5
d = 196 <==
3. A = L * W
when L = 2 ft and W = 15 inches....this one u have to convert to inches...2 ft = 24 inches...so L = 24 and W = 15
A = 24 * 15
A = 360 in^2 <==
4. A = L * W
L = 3m and W = 32 cm...have to convert to cm.....1 m = 100 cm...so 3 m = 300 cm
A = 300 * 32
A = 9600 cm^2 <==
u basically do the same for all the others....its just a matter of subbing and solving
