QUESTION 1:

Required angles are: m<2=75°, m<3=75°, m<4= 105°, m<5= 105°, m<6=75°, m<7=75°, m<8=105°

QUESTION 2:

Required angles are: m<1=100° m<2=80°, m<4= 100°, m<5= 100°, m<6=80°, m<7=80°, m<8=100°

Step-by-step explanation:

Question 1:

if m<1 =105°

We need to find the remaining angles.

The corresponding angles of a traversal are same. so the corresponding angle of <1 is angle 5 So, m<5 = 105°

The vertical angles are also equal. so, vertical angle of <1 is <4. So, m<4 = 105°

Vertical angles of m<5 is m<8 so, m<8=105°

m<1 and m<2 are supplementary angles of each other so their sum will be equal to 180°

So, m<1+m<2=180

105+m<2=180

m<2=75°

Same goes for m<3 and m<4 so, m<3 = 75°

m<5 and m<6 so, m<6 = 75°

m<7 and m<8 so, m<7= 75°

So, required angles are: m<2=75°, m<3=75°, m<4= 105°, m<5= 105°, m<6=75°, m<7=75°, m<8=105°

Question No 2

if m<3=80°

We need to find the remaining angles.

The corresponding angles of a traversal are same. so the corresponding angle of <3 is angle 7 So, m<7 = 80°

The vertical angles are also equal. so, vertical angle of <3 is <2. So, m<2 = 80°

The Vertical angle of <7 is <6 so, m<6= 80°.

m<1 and m<2 are supplementary angles of each other so their sum will be equal to 180°

So, m<1+m<2=180

m<1+80=180

m<1=100°

Same goes for m<3 and m<4 so, m<4 = 100°

m<5 and m<6 so, m<5 = 100°

m<7 and m<8 so, m<8= 100°

So, required angles are: m<1=100° m<2=80°, m<4= 100°, m<5= 100°, m<6=80°, m<7=80°, m<8=100°

Question number 3 pls

marissa [1.9K]

Factoring f(x) would give a factor (x-1-2i), so you can divide f(x) by this, leaving (x-3)(x+4)(x-1+2i), so the other roots are:

x=3
x=-4
x=1-2i

Elena L [17]

The trinomial did she factor is $\rm x^2-4x-12$ .

Given

Leonora is factoring a trinomial.

The factors of the trinomial are shown on the model.

<h3>Quadratic equation</h3>

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there.

Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

Algebra tiles are tiles used to represent variables or numbers and are rectangular or square-shaped.

1 is labeled + x squared, this gives x².

And 6 are labeled negative. 3 tiles are in the Factor 2 spot:

1 is labeled x and 2 are labeled. 0 tiles are in the Product spot.

-6x + 2x -12

Therefore

The trinomial did she factor is;

$\rm x^2-4x-12$

Hence, The trinomial did she factor is $\rm x^2-4x-12$ .

Factor the following...<br> <img src="https://tex.z-dn.net/?f=9n%5E2-34n-8" id="TexFormula1" title="9n^2-34n-8" alt="9n^2-34n-8"

fredd [130]

Step-by-step explanation:

9x8= 72

therefore 36 x 2 are the products

9 n^2 - 36n + 2 n -8

9 n( n-4) + 2( n- 4)

therefore the two factors are

( 9 n +2) ( n-4)
