Answer:

49,45$

Step-by-step explanation:

15 : 100 = x : 43

x = (43 * 15) / 100 = 6,45

43 + 6,45 = 49,45$

Mrac [35]

Answer:

71.6 degrees

Step-by-step explanation:

Given the vectors

u= <8,4> v = <9.-9> (5 points)

u*v = (8, 4)*(9, -9)

u*v = 8(9)+(4)(-9)

u*v = 72 - 36

u*v = 36

|u| = √8²+4²

|u| = √64+16

|u| = √80

|v| = √9²+9²

|v|  = √81+81

|v|  = √162

Using the formula

u*v = ||u||v| cos theta

36 = √80(√162)cos theta

36 = √12960 cos theta

cos theta = 36/√12960

cos theta = 36/113.8

cos theta = 0.3162

theta = arccos(0.3162)

theta = 71.56 degrees

Hence the angle between the given vectors to the nearest tenth of a

degree is 71.6 degrees

What is the value of tan (B) in the diagram?
hodyreva [135]

Answer:

The correct answer is third option

1/√3

Step-by-step explanation:

From the figure we can see a right angled triangle ABC.

Right angled at C.

AB = 10

AC = 5

BC = 5√3

<u>Points to remember</u>

Tan θ = Opposite side/Adjacent side

<u>To find the value of tan(B)</u>

Tan B =  Opposite side/Adjacent side

 = AC/BC

 = 5/5√3

 = 1/√3

Therefore the value of tan(B) =  1/√3

What is the value of x?
Ronch [10]

Answer:

x = 10

Step-by-step explanation:

Consecutive angles in a parallelogram are supplementary, thus

∠ A + ∠ B = 180, substitute values

9x + 8 + 8x + 2 = 180, that is

17x + 10 = 180 ( subtract 10 from both sides )

17x = 170 ( divide both sides by 17 )

x = 10
