Hi there!

To solve this problem, we need to find x, and plug it into measure c to get the value of c.

First, let's find x.

Since we know that the sum of all measures of a triangle is always equal to 180 degrees...

6x + 2x + 2x = 180
10x = 180
x = 18

Now, let's plug it in.

2x
= 2*18
= 36

So, measure c is 36 degrees.

Hope this helps!

2x+2x+6x=180
10x=180
x=18

m∠C = 2x =2*18=36

Apply Newton’s method to estimate the solution of x3 − x − 1 = 0 by taking x1 = 1 and finding the least n such that xn and xn +
ss7ja [257]

Solution :

Given

$f(x)=x^3-x-1, x_1=1$

$f'(x)=3x^2-1$

Let the initial approximation is $x_1 =1$

So by Newton's method, we get

$x_{n+1}=x_n-\frac{f(x_n)}{f'(x_n)},n=1,2,...$

$x_2=x_1-\frac{f(x_1)}{f'(x_1)}=1-\frac{1^3-1-1}{3(1)^2-1}=1.5$

$x_3=1.5-\frac{(1.5)^3-1.5-1}{3(1.5)^2-1}=1.34782608$

$x_4=1.34782608-\frac{(1.34782608)^3-1.34782608-1}{3(1.34782608)^2-1}=1.32520039$

$x_5=1.32520039-\frac{(1.32520039)^3-1.32520039-1}{3(1.32520039)^2-1}=1.32471817$

$x_6=1.32471817-\frac{(1.32471817)^3-1.32471817-1}{3(1.32471817)^2-1}=1.32471795$

$x_5 \approx x_6$ are identical up to eight decimal places.

The approximate real root is x ≈ 1.32471795

∴ x = 1.32471795

convert the linear equation 3x-2y=5 to point slope form. use the point with an x-coordinate equal to 1
Mademuasel [1]
When x = 1,  y = (5 - 3) / -2  = -1 ,  let x1 = 1 and y1 = -1
2y = 3x - 5
so slope = 3/2

y - y1 = m(x - x1)

y -(-1) = (3/2)(x - 1)

y + 1 = 3/2 ( x - 1)  <-----    answer
