Find the values of each variables in each quadrilateral. ​
Ahat [919]
First lets solve for x we know 3x=90. In this case x=30. Now we can solve for y. We know the triangle needs to equal 180 so y+2(30)=180. So we get y=120. Hope it helps

Find the value of x.<br><br><br>m∠IHG = 162°<br><br>m∠IHK = (4x + 4)°<br><br>m∠KHG = (8x + 2)°
kirill [66]

Answer:

1

Step-by-step explanation:

<IHG = 162

<IHK = 4x + 4

<KHG = 8x + 2

<IHG + <IHK + <KHG = 180° (sum of angles in a triangle is equal to 180°)

See attachment for better illustration of the triangle

162 + (4x + 4) + (8x + 2) = 180

162 + 4x + 4 + 8x + 2 = 180

168 + 12x = 180

Collect liketerms

12x = 180 - 168

12x = 12

x = 1

A polynomial equation with rational coefficients has the roots -8 and 2-i. Find two additional roots
shutvik [7]

Answer:

Step-by-step explanation:

If the polynomial is a cubic (third-degree), then it is

f(x) = x³+4x²-27x+40

and the other root is 2+i.

However, if we need two additional roots, it implies that the polynomial is a quartic (fourth degree).  In that case, we need additional information.  Reread the original question and  update post if necessary.

Describe the process of rewriting the expression Please Help
Mazyrski [523]

Answer:

x^{\frac{21}{4} }

Step-by-step explanation:

Given expression is:

(\sqrt[8]{x^7} )^{6}

First we will use the rule:

\sqrt[n]{x} = x^{\frac{1}{n} }

So for the given expression:

\sqrt[8]{x^{7}}=(x^{7} )^{\frac{1}{8} }

We will use tha property of multiplication on powers:

=x^{7*\frac{1}{8} }

= x^{\frac{7}{8} }

Applying the outer exponent now

(x^{\frac{7}{8} })^6

= x^{\frac{7}{8}*6 } \\= x^{\frac{42}{8} }\\= x^{\frac{21}{4} }
