The sum of the measures of the angles of a triangle is 180°. The middle-sized angle measures 3° more than 2 times the smallest angle. The middle-sized angle measures 109° less than the largest angle. Find the measure of each angle.​

Answers

Answer 1

Answer:

13° , 29° , 138°

Step-by-step explanation:

let x be the smallest angle , then

2x + 3 is the middle angle and

2x + 3 + 109 is the largest angle

summing the 3 angles and equating to 180

x + 2x + 3 + 2x + 3 + 109 = 180 , that is

5x + 115 = 180 ( subtract 115 from 180 )

5x = 65 ( divide both sides by 5

x = 13

2x + 3 = 2(13) + 3 = 26 + 3 = 29

2x + 3 + 109 = 29 + 109 = 138

the 3 angles are 13° , 29° , 138°

Now, (1-tan²x)+sec²x

Now, evaluate [tex]\frac{sec^{2}-4 }{sec+2}[/tex]

As per definition:Complementary angles are adjacent angles that sum to 90°;Supplementary angles are adjacent angles that sum to 180°.

Now, ORQ is a straight angle and RS its bisector.

It means:

ORS = QRS = 180°/2 = 90°

So, ∠ORS and ∠QRS are supplementary.

We also have ray RP, that divides the angles ORQ and QRS.

It gives us one more pair of supplementary angles:

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

Answers

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.

What is the polynomial?

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.

Answer:

y = (-3/2)x

Step-by-step explanation:

I am going to answer this question in slope-intercept form, which is y = mx + b (m is the slope, b is the y-intercept). The question already gives us the y-intercept, or the point at which the graph crosses the y-axis. It is (0, 0). Now, all we have to do is find the slope, which we can do using the following formula:

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

In this formula, (x1, y1) and (x2, y2) are two points that are given to us [the first point is (0,0) and the second point is (2,-3). We can solve for the slope by plugging in:

[tex]m=\frac{-3-0}{2-0}=\frac{-3}{2}[/tex]

Now that we have m and b, we can plug into slope-intercept form to get our equation: y = (-3/2)x + 0 or y = (-3/2)x

How to solve the system of equations?

The system of equations is given as:

Multiply the first equation by 2 and the second by 5.

Subtract the above equations

10x - 10x + 4y - 15y = 6 - 50

This gives

y = 4

Substitute y = 4 in 5x + 2y = 3

From the zephyr's wingExhales the incense of the blooming spring.Soft purl the streams; the birds renew their notes,And through the air their mingled music floats.Through all the heav'ns what beauteous dies are spread!But the west glories in the deepest red:So may our breasts with ev'ry virtue glow,The living temples of our God below.Fill'd with the praise of him who gives the lightAnd draws the sable curtains of the night,Let placid slumbers sooth each weary mindAt morn to wake more heav'nly, more refin'd;So shall the labours of the day beginMore pure, more guarded from the snares of sin.Night's leaden sceptre seals my drowsy eyes;Then cease, my song, till fair Aurora rise.Nature is a recurring theme in early American literature.

What type of speech organizational pattern would Annie use A solution containing 1 mol of a strong electrolyte will have a(n) _____ effect on the colligative properties of the solution than 1 mol of a nonelectrolyte. A strong electrolyte will dissociate or ionize in aqueous solution, and therefore the total number of dissolved solute particles is _____ for 1 mol of a strong electrolyte than for 1 mol of a nonelectrolyte solute. In conducting a case-control study researchers consistently mislabel study participants such that unexposed cases are labeled as being exposed more often than the unexposed controls are labeled as being exposed. What effect would this have on our Odds Ratio
