NEED HELLP ASAP !!!

Answer:

m<x = 48

m<y = 132

Step-by-step explanation:

Since x and y are supplementary angles, that means their sum is 180 degrees.

And we are given that y is 12 less than 3 times the measure of x. With this information we can make a system of linear equations.

x + y = 180

y = 3x - 12

So now plug in the value of y into the first equation.

x + y = 180

x + (3x - 12) = 180

x + 3x = 192

4x = 192

x = 48

And then plug this computed value of x back into the first equation to find the measure of y.

x + y = 180

48 + y = 180

y = 180 - 48

y = 132

So the measures of the angles are as follows:

m<x = 48

m<y = 132

Which equation of the solutions of x2 = -7x – 8

timama [110]

Answer:

x = 1, -5.56

Step-by-step explanation:

x^2 = -7x - 8

shift -7x and -8 to the other side . Remember when u shift minus changes into plus.

x^2 + 7x + 8 = 0

using quadratic equation formula

in quadratic equation one value comes positive and other comes in negative

a = 1 , b = 7 and c = 8

taking positive sign

x = (-b + $\sqrt{b^2 - 4*a*c}$ ) /2*a

x = (-7 + $\sqrt{7^2 - 4*1*8}$ ) /2*1

x = (-7 + $\sqrt{49 + 32}$ ) /2

x = (-7 + $\sqrt{81}$ )/ 2

x = -7 + 9 / 2

x = 2/2

x = 1

taking negative sign

(-b - $\sqrt{b^2 - 4*a*c}$ ) /2*a

x = (-7 - $\sqrt{7^2 - 4*1*8}$ ) /2*1

x = (-7 - $\sqrt{49 - 32}$ ) /2

x = -7 - $\sqrt{17}$ / 2

x = -7 - 4.12 / 2

x = -11.12/2

x = -5.56

therefore x = 1 , - 5.56

Answer:

This is a vertical angle theorem

Step-by-step explanation:

Vertical angles are a pair of opposite angles formed by intersecting lines. In the figure, ∠1 and ∠3 are vertical angles. ... Vertical angles are always congruent . So, in this figure, ∠1≅∠3 and ∠2≅∠4 .
