Answer:

28

Step-by-step explanation:

Since the triangle is a right triangle, we can use SOH CAH TOA to find ?. 10 is OPPOSITE to ? and 21 is HYPOTENUSE to ?, so we can use SIN to find ?.


SIN(?) = 10/21

? = ARCSIN(10/21)

? = 28.437

= 48 2/3 + 30 1/2

= 48 4/6 + 30 3/6

= 48 + 7/6

Type the correct answer in each box. Round your answers to two decimal places. Subtract vector v = <2, -3> from vector u =
expeople1 [14]

u - v = <5, 2> - <2, - 3> = <5 - 2, 2 + 3> = <3, 5>

given a vector <u, v> then the magnitude is √ (u² + v² ) and it's angle of direction is

θ = tan^{-1}(\frac{v}{u})

thus the magnitude of <3, 5> = √(3² + 5²) = √34 ≈ 5.83 ( to 2 dec. places )

Θ = tan^{-1}(\frac{5}{3}) = 59.04° ( to 2 dec. places )

If √6 is the geometric mean between 4 and another number, then the number is
joja [24]
If you have two numbers x, y.  The geometric mean is:  √xy

For 4 and x.  Geometric Mean =  √4x  and this is equal to √6

             √4x  =  √6     Square both sides.  The square root disappears.

               4x = 6 
                 x  = 6/4 = 3/2 = 1.5

The other number is 1.5.
