Given: circle k(O), ED diameter, m∠OEF=32°, m EF=(2x+10)°. Find: x

Snezhnost [94]

Answer:

The value of x is $53\°$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of arc DF

we know that

The inscribed angle measures half that of the arc comprising

so

$m$

we have

$m$

substitute

$32\°=\frac{1}{2}(arc\ DF)\\ arc\ DF=64\°$

step 2

Find the measure of x

we know that

$arc\ DF+arc\ EF=180\°$ ---> is a semi circle

we have

$arc\ DF=64\°\\ arc\ EF=(2x+10)\°$

substitute

$64\°+(2x+10)\°=180\°\\ 2x\°=180\°-74\°\\ 2x\°=106\°\\ x=53\°$

When solving a system of equations graphically, when would you need to estimate the solution? Explain

SashulF [63]

Answer:

To solve an equation means to find all the values that should satisfy the given statement. To solve an equation graphically, draw the graph for x and y of the given equation and notice where the curves cuts should be equal.

Step-by-step explanation:

Solving system of linear equations by using graph:

A system of linear equations contains atleast two equations.For example y=5x+2 and y=x.The solution of both equations can be denoted as a ordered pair.To solve the system of linear equations we have to plot the points in the graph for both equations in coordinate system must be same.The intersection of two straight lines is the solution(point) for the given system.

A line passes through the points (7, 10) and (7, 20). Which statement is true about the line? It has a slope of zero because in

geniusboy [140]

Slope formula: $\frac{y2-y1}{x2-x1}$
Apply.
$\frac{20-10}{7-7} = \frac{10}{0} =$ undefined (No slope)

Thus, that answer is: Choice D.

If you're wondering why C isn't this answer, it's because it doesn't matter if 0 is the numerator of a fraction. If it was, then the slope would be 0 regardless. However, if 0 takes place in the denominator, the slope will be undefined; there will be no slope.

I NEED HELP PLEASE VERY QUICKLY WITH WORK SHOWN

Pavel [41]

Answer:

The measure of angle 2 is 110 degrees

Step-by-step explanation:

Step 1: Find the value of x

Since angle 1 and angle 2 are complimentary, that means they add up to 180.

2x + 3x + 5 = 180

Step 2: Solve for x

2x + 3x + 5 = 180

5x + 5 - 5 = 180 - 5

5x / 5 = 175 / 5

x = 35

Step 3: Find the measure of angle 2

m<2 = 3x + 5

m<2 = 3(35) + 5

m<2 = 110

Answer: The measure of angle 2 is 110 degrees
