Answer:

< - 52, 48 > and 70.77

Step-by-step explanation:

2v - 6u

= 2<- 11, 3 > - 6 < 5, - 7 >

= < - 22, 6 > - < 30, - 42 >

= < - 52, 48 >

| 2v - 6u | = \sqrt{(-52)^2+(48)^2} = \sqrt{5008} = 70.77

Given: Circumscribed polygon ABCD AB=21, BC=24, CD=30 Find: AD AD = ____ units
dolphi86 [110]

Answer:

AD = 27 units

Step-by-step explanation:

In the above question, we have a circumscribed Polygon, were circle XYZ is inside the polygon ABCD

We were given the following side

AB=21 units

BC=24 units

CD=30 units

Side AB = AW + BW

21 units = x + 21 - x

Side BC = BX + CX

BX = BW , hence BX = 21 - x

Side BC = 21 units

24 = 21 - x + CX

CX = 24 - (21 - x)

CX = 24 - 21 + x

CX = 3 + x

Side CD = CY + DY

Note that: CY = CX, hence, CY = 3 + x

Side CD = 30 units

30 = 3 + x + DY

DY = 30 - (3 + x)

DY = 30 - 3 - x

DY = 27 - x

Side AD = AZ + DZ

Note also that:

AZ = AW , hence AZ = x

DY = DZ , hence DZ = 27 - x

Side AD = x + 27 - x

Side AD = 27 units

Common denominators! 

<span>If you have to add... 3 fractions with 4 as the denominators: </span>
<span>Then you can combine the numerators: </span>

<span>a/c+ b/c = (a+b)/c and a/d + b/d + c/d = (a+b+c)/d </span>

<span>Let's plug in the numbers.</span>

<span>a=3, b=1, c=1, d =4 </span>
<span>3/4 + 1/4 + 1/4 = 5/4 or 1 1/4! </span>

<span>So the equation for the problem: </span>

<span>Lt = L1+ L2 + L3 + L4 or </span>
<span>L4 = Lt - L1 - L2 - L3 Plug in the numbers </span>

<span>L4 ( remains ) = L total, 72 - L1 ( first cut at 30 3/4 ) - L2 ( second cut 12 1/4 ) - L3 ( 16 1/4 ) </span>

<span>So 72 - 30 - 12 - 16 - 3/4 - 1/4 - 1/4 =? </span>
<span>( break this down into simple terms and do it in your head... </span>

<span>72 - 30 = 42, 42 - 21 = 30, 30 - 16 = 14, 14 - 3/4 = 13 1/4 - 1//4 = 13 - 1/4 = 12 3/4!</span>

The black triangles are similar. Identify the type of segment shown in blue and find the value of the variable. altitude base hy
Shtirlitz [24]

Answer:

Hello your question is incomplete attached below is the complete question

answer : ALTITUDE , x = 24

Step-by-step explanation:

The type of segment shown in Blue is ALTITUDE segment

This is because

Angle BCD = Angle CEG (opposite angles)

Angle ACD= Angle CFG (opposite  angles)

Angle ADC = Angle BCD= Angle CEG = Angle CFG

It can be seen that the triangles are similar hence

 18/27=16/x

therefore  X  =24
