Answer:

x = 6.928

Step-by-step explanation:

Since we don't know the hypotenuse, we will use tan

tanΘ = opposite/adjacent     (Θ = theta, which is basically the variable for an angle)

tan30° = x/12

to find x, multiply 12 to the other side

12tan30° = x            (plug this into a calculator)

x = 6.928

IfA=(-2,-4) and B=(-8,4), what is the length of AB?
lisabon 2012 [21]

Answer:

<h2>10 units </h2>

solution,

A(-2,-4)--->(X1,y1)

B(-8,4)----->(x2,y2)

now,

ab =  \sqrt{(x2 - x1) ^{2}  +  {(y2 - y1)}^{2} }  \\  \:  \:  \:  \:  =  \sqrt{ (- 8 - ( - 2)) ^{2} + (4 - ( - 4))  ^{2} }  \\  \:  \:  \:  =  \sqrt{( - 8 + 2) ^{2} +  {(4 + 4)}^{2}  }  \\  \:  \:  \:  =  \sqrt{( - 6) ^{2} +  {(8)}^{2}  }  \\  \:  \:  =   \sqrt{36 + 64}  \\  \:  \:  \:  =  \sqrt{100}  \\  \:  \:  \:  =  \sqrt{ {(10)}^{2} }  \\  \:  \:  \:  \:  = 10 \: units

Hope this helps..

Good luck on your assignment

Helppppppppppp please am struggling
AURORKA [14]

Answer:

x = 60°

Step-by-step explanation:

The circle is 360°, thus

2y + y = 360

3y = 360 ( divide both sides by 3 )

y = 120°

The tangent- secant angle ABT is one half the measure of the intercepted arc AB, thus

x = 0.5 × 120° = 60°

PLEASE HELP WITH EXPLANATION <br><br> F(x) = 3 - x; g(x) = -2x <br><br> find f(g(2))
ioda

Given,

f(x) = 3 - x

and

g(x) = -2x

Now,

g(2) =  - 2(2) =  - 4

f(g(2)) = 3 - ( - 4) = 3 + 4 = 7
