Can someone help me find the value of x?

tensa zangetsu [6.8K]

Answer:

The measure of arc x is $60\°$

Step-by-step explanation:

we know that

The measurement of the external angle is the semi-difference of the arcs it comprises.

In this problem

$55\°=\frac{1}{2}(170\°-x\°)$

solve for x

$110\°=(170\°-x\°)$

$x\°=(170\°-110\°)=60\°$

Find the roots of the polynomial equation. 2x3 + 2x2 – 19x + 20 = 0

d1i1m1o1n [39]

First, find any zero of the polynomial. Since you didn't ask for work, I'll assume it's okay if I use my calculator. Your given polynomial has only one real root which is x=-4.

Now we use the rule that x-a divides the polynomial where a is a zero of said polynomial.

So x+4 divides 2x^3+2x^2-19x+20.
(2x^3+2x^2-19x+20) / (x+4 equals 2x^2-6x+5).

If we factor out a two, we can use the quadratic formula.

2(x^2-3x+2.5) so we have x = (-(-3)+/-(9-4*1*2.5)^(1/2))/2*1)=(3+i)... or (3-i)/2 Where i is the square root of negative one. final answer:
2x^3+2x^2-19x+20=0

then x=-4, (3+i)/2, or (3-i)/2
we have two imaginary number.
I hope it helped you

Simplify help please

Advocard [28]

Answer:

x = 85

Step-by-step explanation:

The Pythagorean theorem is a property that is specific to right triangles, or triangles with a right angle. The Pythagorean theorem states the following,

$a^2 + b^2 = c^2$

Where (a) and (b) are the legs or the sides adjacent to the right angle, and (c) is the hypotenuse or side opposite the right angle.

Substitute in the given values and solve,

$13^2 + 84^2 - x^2\\\\169 + 7056 = x^2\\\\7225 = x^2\\\\85 = x$
