Hello there.
<span>Solve for p: a = 2πpw
</span>
< ABD + > ABC = 180.....because these angles form a linear pair
2x + 5x + 5 = 180
7x + 5 = 180
7x = 180 - 5
7x = 175
x = 175/7
x = 25
< ABC = 5x + 5......5(25) + 5 = 130 <==
Answer:
p = 5 and b = 8
Step-by-step explanation:
First, create a system of equations:
2p + 4b = 42
7p + 9b = 107
Solve by elimination by multiplying the top equation by -7 and the bottom equation by 2:
-14p - 28b = -294
14p + 18b = 214
Add these together, and solve for b:
-10b = -80
b = 8
Plug in 8 as b into one of the equations, and solve for p:
2p + 4b = 42
2p + 4(8) = 42
2p + 32 = 42
2p = 10
p = 5
So, p = 5 and b = 8
Answer:
ED = 32.5
BE = 14.4
Step-by-step explanation:
Ab = 20
AC = AB + 5 = 20 + 5 = 25
AC / AB = 1.25
AB * 1.25 = AC
This means that:
AE * 1.25 = ED
CD / 1.25 = BE
AE * 1.25 = ED
26 * 1.25 = 32.5
CD / 1.25 = BE
18 / 1.25 = 14.4
