Answer:   12. x =7           13. x =6

Step-by-step explanation:

Both angles in the triangle has to equal to each other because they are both equivalent.

Set both expressions equal to each other and solve for x.  

12.  5x =  35    Divide both sides by 5

x =  7  

13.     3x =   5x - 12      Subtract 5x from both sides

        -5x       -5x  

   -2x =  -12      Divide both sides by -2

 x = 6

WILL GIVE BRAINLIEST!<br> Find x given y = 76° in the figure below.<br> x = <br> °
4vir4ik [10]

Answer:

104°

Step-by-step explanation:

The straight line for q forms an angle of 180°

Therefore,

x+y=180

x+76=180

x=180-76

x=104

How can you quickly determine the number of roots a polynomial will have by looking at the equation?
Shtirlitz [24]

One can determine the number of roots by seeing the degree of the given polynomial.

The number of roots can be determined by just seeing the highest power of the given equation.

1) for the equation  x-4=0

here, the highest power of the equation is one. So, it will have one root.

<h3>What is the polynomial?</h3>

A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtract multiplication, on,  and non-negative integer exponentiation of variables.

Let's check it by simplifying x-4=0  which implies x=4

Hence, the equation has only one root namely x = 4.

2) Consider a quadratic equation,

10t^2-t-3=0

here, the highest power of the equation is two. So, it will have two roots.

Let's check it by simplifying using the middle term splitting method,

10t^2+5t-6t-3=0

5t(2t+1)-3(2t+1)=0

(5t-3)(2t+1)=0

t=-3/5 or t=-1/2

Thus, the equation has two roots.

Hence, one can determine the number of roots by seeing the degree of the given polynomial.
