Answer: The first and second angles measure 54 degrees each. The third angle measures 72 degrees.

Step-by-step explanation:

First, I transcribed the sentences into equations.

The first part of the sentence says that "two angles of a triangle have equal measures", and we can use the konwledge that the interioir angle sum of all triangles in 180 degrees to solve this.

Lets call the first and second angles x and the third angle y. Then we can get the equation that 2x + y = 180. You might be asking "where did the 2x come from?", well, we know that if we add all of the angles up we get 180 degrees, and since two of the angles are equal, they can be simplified to 2x.

The second part of the sentence says that "the third angles measure is 36 degrees less than the sum of the other two", which translates to:

y = 2x - 36

Then we can substitute the second equation into the first and solve!

2x + (2x - 36) = 180

4x - 36 = 180

4x = 216

x = 54

Knowing that x = 54, we can substitute back into the first equation to solve for y. 2(54) + y = 180, 108 + y = 180, y = 72.

Which values of c will cause the quadratic equation –x2 3x c = 0 to have no real number solutions? check all that apply.
nika2105 [10]

The given quadratic equation will not have any real solution for c<-9/4.

The given quadratic equation is:

-x^{2} +3x+c=0

<h3>What is a quadratic equation?</h3>

Any equation of the form ax^{2} +bx+c=0 is called a quadratic equation with a≠0.

In order to have no real solution, the discriminant of a quadratic equation will be less than zero.

D < 0

3^{2} -4(-1)(c) < 0

9+4c < 0

c < -\frac{9}{4}

For c < -\frac{9}{4} the given quadratic equation will have no real solutions.

Hence, the given quadratic equation will not have any real solution for c<-9/4.

Alex has 209 coins. Of the coins, 5/11 are nickels, 5/11 are dimes, and rest are quarters. What is the ratio of Alex’s nickels t
vodka [1.7K]

Answer:

95:95:19

Step-by-step explanation:

1.Divide 209 by 11.(209÷19)

2.Multiply 19×5 since 5/11 of the coins are nickels.(19×5=95)

3.Multiply 19×5 again since 5/11 of the coins are dimes.(19×5=95)

4.Multiply 19×1 since there would be 1/11 left of the coins which are quarters. (19×1=19)

5.Check your awnser by adding 95+95+19.(95+95+19=209)

Please help me out with this!!<br> BRAINLIEST AVAILABLE!!
lapo4ka [179]

Answer:

xy = 1

k = 79

Step-by-step explanation:

Question One

The first and third frames look to me to be the same. I'll treat them that way.

y = x^2                        Equate y = x^2 to the result of 2y + 6 = 2x + 6

2y + 6 = 2(x + 3)         Remove the brackets

2y + 6 = 2x + 6           Subtract 6 from both sides

2y = 2x                       Divide by 2

y = x

Now solve these two equations.

so x^2 = x                  

x > 0

1 solution is x = 0 from which y = 0. This won't work. x must be greater than 0. So the other is

x(x) = x                           Divide both sides by x            

x = 1                            

y = x^2                           Put x = 1 into x^2

y = 1^2                           Solve

y = 1                      

The second solution is

(1,1)

xy = 1*1

xy = 1

Answer: A

Question Two

square root(k + 2) - x = 0

Subtract x from both sides

sqrt(k + 2) = x                Square both sides

k + 2 = x^2                    Let x = 9

k + 2 = 9^2                    Square 9

k + 2 = 81

k = 81 - 2

k = 79
