6 0

Answer:

measure of each base angle =  80 each angle

measure of vertex angle = 20

Step-by-step explanation:

x=base angle    

2x+ x/4= 180

Multiply everything by 4 to eliminate the fraction

8x+x = 720

9x=720

x=80

80/4=12

<h2>Using the quadratic formula</h2>

The quadratic formula can help us solve for x in a quadratic equation:

x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}

We can use this when the given equation is organized in standard form: ax^2+bx+c=0

<h3>Applying this to the problem</h3>

2x^2+5x-4=0

First we can identify the values of a, b and c:

a = 2

b = 5

c = -4

Plug these values into the quadratic formula:

x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}

x=\dfrac{-5 \pm \sqrt{5^2-4(2)(-4)}}{2(2)}

x=\dfrac{-5 \pm \sqrt{25+32}}{4}

x=\dfrac{-5 \pm \sqrt{57}}{4}

<h2>Answer</h2>

Therefore, the two possible values of x are:

x=\dfrac{-5 +\sqrt{57}}{4}

x=\dfrac{-5 -\sqrt{57}}{4}

What are the length of each side of a quadrilateral when the perimeter is 33 and the sides are:
solong [7]
Answer: 
A = 6 
So 
Side A = 6 
Side B = 11 
Side C = 3 
Side D = 13

Explanation: 
To solve perimeter of a quadrilateral, you use this formula: 
side A + side B + side C + side D = total perimeter.

If the four sides are A, A + 5, A – 3, and 2A + 1 then you need to solve for A.

Write out an algebraic formula with these values:
A + (A + 5) + (A – 3) + (2A + 1) = P 
You also know that the total perimeter is 33, so :
A + (A + 5) + (A – 3) + (2A + 1) = 33 
You can add all the A values together to combine like terms like this:
5A + 5 – 3 + 1 = 33 
Solve fore A:
5A + 3 = 33 
5A = 33 – 3 
5A = 30 
A = 30 ÷ 5 
A = 6 

Check your answer: 
A + (A + 5) + (A – 3) + (2A + 1) = 33 
(6) + ((6) + 5) + ((6) – 3) + (2(6) + 1) = 33 
(6) + (11) + (3) + (13) = 33 
17 + 16 = 33 
33 = 33
