Answer:

x = 8.4 cm

Step-by-step explanation:

Here we have to use the tan ratio to find the value of x.

tan = opposite/adjacent

tan 35 = x/12

Multiplying both sides by 12, we get

x = 12 tan 35               [tan 35 = 0.7]

x = 12*0.7

x = 8.4

Therefore, the value of x = 8.4 cm

Hope this will helpful.

Thank you.

Tan(35)=x/12
.7=x/12
12*.7=x
x=8.4

Divide -3x^3-2x^2-x-2 by x-2
Rasek [7]

Let's do this by Briot-Ruffini


First: Find the monomial root


x - 2 = 0

x = 2


Second: Allign this root with all the other coeficients from equation

Equation = -3x³ - 2x² - x - 2

Coeficients = -3, -2, -1, -2

2 | -3 -2 -1 -2


Copy the first coeficient


2 | -3 -2 -1 -2

-3


Multiply him by the root and sum with the next coeficient


2.(-3) = -6

-6 + (-2) = -8


2 | -3 -2 -1 -2

-3 -8


Do the same


2.(-8) = -16

-16 + (-1) = -17


2 | -3 -2 -1 -2

-3 -8 -17


The same,


2.(-17) = -34

-34 + (-2) = -36


2 | -3 -2 -1 -2

-3 -8 -17 -36


Now you just need to put the "x" after all these numbers with one exponent less, see


2 | -3x³ - 2x² - 1x - 2

-3x² - 8x - 17 -36


You may be asking what exponent -36 should be, and I say:


None or the monomial. He's like the rest of this division, so you can say:


(-3x³ - 2x² - x - 2)/(x - 2) = -3x² - 8x - 17 with rest -36 or you can say:

(-3x³ - 2x² - x - 2)/(x - 2) = -3x² - 8x - 17 - 36/(x - 2)


Just divide the rest by the monomial.

5+2x+6=x +10 <br> Solve this equation and show ur work
Rama09 [41]

Answer:

x = -1

Step-by-step explanation:

5 + 2x + 6 = x + 10

11 + 2x = x + 10

      -x      -x

11 + x = 10

-11          -11

x= -1

Need answer to this math problem
Elis [28]

The slope of this line is the difference of the y values divided by the difference of the x values. Solving this give 4/-3. Then, you already know the b in y = mx+b, which is 2, because you already have the value (0, 2). So, the answer is y = -\frac{4}{3}x + 2
