Answer:

x = 60°

Step-by-step explanation:

First find <E by applying the angles of intersecting chords theorem.

Based on the theorem, we would have the following equation:

m<E = ½(arc CA + arc BD)

Substitute

m<E = ½(170° + 70°)

m<E = ½(240)

m<E = 120°

Let's find x:

x = 180° - m<E (supplementary angles)

x = 180° - 120° (substitution)

x = 60°

What is the solution to the equation One-fourth x + 2 = negative StartFraction 5 Over 8 EndFraction x minus 5? X = negative 8 x

Ede4ka [16]

Answer:

$(A)x= -8$

Step-by-step explanation:

One-fourth x + 2 = $\frac{1}{4}x+2$

$\frac{1}{4}x+2=-\frac{5}{8}x-5$

Next, we Expand the Left hand Side by multiplying each term in the bracket by 1/4

$\frac{1}{4}x+\frac{2}{4}=-\frac{5}{8}x-5$

Bringing terms with x to the left Hand Side i.e. collecting like terms

$\frac{1}{4}x+\frac{5}{8}x=-5-2\\\\(\frac{1}{4}+\frac{5}{8})x=-7\\\\\frac{7}{8}x=-7$

On Cross multiplying

7x = -7 X 8

$x=-\dfrac{7*8}{7}\\$

x=-8

If two points known on the line AB in the coordinate plane is (7,15) and (18,42), calculate the following..

Ksju [112]

Answer:

Slope = 27/11
AB = 29.15 u

Step-by-step explanation:

Given :-

Two points are given to us .
The points are A(7,15) and B(18,42)

To Find :-

The slope of the line .
The length of line AB .

We can find the slope of the line passing through the points $( x_1,y_1)$ and $( x_2,y_2)$ as ,

$\implies m = \dfrac{ y_2-y_1}{x_2-x_{1}}$

Plug in the respective values ,

$\implies m = \dfrac{ 42-15}{18-7} \\\\\implies \boxed{ m = \dfrac{ 27}{11 }}$

Hence the slope of the line is 27/11 .

$\rule{200}2$

Finding the length of AB :-

We can find the distance between them by using the Distance Formula .

$\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2} \\\\\implies Distance =\sqrt{ (18-7)^2+(42-15)^2 } \\\\\implies Distance =\sqrt{ 11^2 + 27^2 } \\\\\implies Distance =\sqrt{ 121 + 729 } \\\\\implies Distance = \sqrt{ 850} \\\\\implies \boxed{ Distance = 29.15 \ units }$
