Answer:

11.9 cm

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relation between the side opposite the angle (BC) and the hypotenuse (14 cm).

Sin = Opposite/Hypotenuse

sin(58°) = BC/(14 cm)

BC = (14 cm)×sin(58°) . . . . . multiply by the denominator

BC ≈ 11.9 cm

Help with number 14 please :))

Answer:

b = - 5

Step-by-step explanation:

(k + a )(k + x) + 1 = k^2 + kx + ak + ax + 1

I think the way to solve this is to worry about the 36

k^s + 1 + ak should equal 36

We know that a = 2

k^2 + 1 + 2k = 36

k^2 + 2k + 1 - 36 = 0

k^2 + 2k - 35 = 0

(k + 7)(k - 5) = 0

k = -7 is the only acceptable answer. It is given that K < 0.

bx = kx + ax

b = k + a

b = - 7 + 2

b = - 5

To solve this equation, the first thing to do would be to simplify. Look at the steps shown below.

$-\frac{1}{2}x + 1 = 7x - 14$

(To make things easier, I will be writing 1/2x as 0.5x)

First isolate x my moving the variables to one side of the equation and the numbers to the other. Please note that when you move them this way, the number or variable must become the opposite of what it currently is for the equation to remain true. The equation will now look like;

$-0.5x - 7x = -1 - 14$
