Option B:
The perimeter of ΔABC is 28 units.
Solution:
AD = 5, DC = 6 and AB = 8
AD and AE are tangents to a circle from an external point A.
BE and BF are tangents to a circle from an external point B.
CD and CF are tangents to a circle from an external point C.
<em>Tangents drawn from an external point to a circle are equal in length.</em>
⇒ AD = AE, BE = BF and CD = CF
AE = 5
AE + BE = AB
5 + BE = 8
Subtract 5 from both sides.
BE = 3
BE = BF
⇒ BF = 3
CD = CF
⇒ CF = 6
Perimeter of the polygon = AE + BE + BF + CF + CD + AD
= 5 + 3 + 3 + 6 + 6 + 5
= 28
The perimeter of ΔABC is 28 units.
Option B is the correct answer.
Answer:
5x4 - 3x2 + 9x - 7
Step-by-step explanation:
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(((5•(x4))+7x)+2)-((3x2-2x)+9)
Step 2 :
Equation at the end of step 2 :
((5x4 + 7x) + 2) - (3x2 - 2x + 9)
Step 3 :
Checking for a perfect cube :
3.1 5x4-3x2+9x-7 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 5x4-3x2+9x-7
Look at the pictures it explains the equation step by step tell me if you have any questions the answer is at the bottom
Answer:
Vertical
Step-by-step explanation:
We can see that the line is parallel to the y-axis. This is an indicator that the line is vertical.
On the other hand, if the line was parallel to the x=axis, it would indicate that it is horizontal.
I hope this helps!
