Answer:

105 degrees

Step-by-step explanation:

The measure of the exterior angle of a triangle is equal to the sum of the measures of the other angles of the triangle.

Given that, we know the missing angle is 25 + 80 = 105.

Select the correct product.

AURORKA [14]

Answer:

Option A. $2x^{3}+7x^{2}+12x-8$

Step-by-step explanation:

we have

$(x^{2}+4x+8)(2x-1)$

Applying the distributive property

$(x^{2}+4x+8)(2x-1) =x^{2}(2x)-x^{2} +4x(2x)-4x+8(2x)-8\\ \\=2x^{3}-x^{2} +8x^{2}-4x+16x-8\\ \\= 2x^{3}+7x^{2}+12x-8$

Answer:

Step-by-step explanation:

1) Calm down, your motivated and determined so you will do awesome!

2) write the date AND the chapter the notes are from

3) Write down EVERYTHING even the stuff your teacher says that you dont need to write down

4) use a highlighter or underline important info, your brain cant memorize everything!

5) draw pictures! math is all about visualization

6) if your teacher is teaching a new concept he/she will definetly give you some examples to write down, make up your own examples and solve them to go beyond

7) abbreviate, teachers talk pretty fast so you may struggle to get everything down, if you abbreviate writing will be faster, just dont forget to make a key for your abbreviations so that you dont forget!

8) ask for help!- the most effective tool in the shelf

9) go online and search up worksheets to do

10) write down in you notebook each step you need to take in order to get the answer.

The x- and y- coordinates of point P on the directed line segment from K to J such that P is Three-fifths the length of the line segment from K to J is (85, 105).

Given

On a coordinate plane, a line is drawn from point K to point J. Point K is at (160, 120) and point J is at (negative 40, 80).

<h3>Coordinates</h3>

The coordinates point any point can be found by using the following formula.

$\rm X=\dfrac{m}{m+n}(x_2-x_1)+x_1\\\\ Y=\dfrac{m}{m+n}(y_2-y_1)+y_1$

The x- and y- coordinates of point P on the directed line segment from K to J such that P is Three-fifths the length of the line segment from K to J is;

$\rm X=\dfrac{m}{m+n}(x_2-x_1)+x_1\\\\ X = \dfrac{3}{3+5}(-40-160)+160\\\\ X = 3 \times (-25)+160\\\\\X = -75+160\\\\ X = 85\\\\\ Y=\dfrac{m}{m+n}(y_2-y_1)+y_1\\\\ Y=\dfrac{3}{3+5}(80-120)+120\\\\Y =- 3\times 5 +`120\\\\Y=-15+120\\\\Y=105$

Hence, the x- and y- coordinates of point P on the directed line segment from K to J such that P is Three-fifths the length of the line segment from K to J is (85, 105).
