Find the value of X.

Mathematics
1 answer:
-Dominant- [34]3 years ago
6 0
To find the value of x we first need to find the missing angle in the triangle.

To do that we are gonna add the angles we already have.

64 + 45 = 109

Angles in a triangle measures 180 so to get the missing angle we are gonna subtract 109 from 180

180 - 109 = 71 deg

The missing angle in the triangle is 71 deg


Angles on a straight line adds up to 10 so to find x we are gonna subtract 71 from 180

180 - 71 = 109 degrees

Therefore x is 109 degrees.

What is the slope of the line that passes through (8,4) and (6,7)?
bija089 [108]
slope=\frac{y_2-y_1}{x_2-x_1}\\\\ 
(x_1,y_1)=(8,4)\\ 
(x_2,y_2)=(6,7)\\\\
 slope=\frac{7-4}{6-8}=\frac{3}{-2}=-\frac{3}{2}\\\\
Slope\ is\ equal\ to\ -\frac{3}{2}.

Solve for x: 2x - 2 > 4x + 6
laiz [17]

Isolate the x. Subtract 4x from both sides, and add 2 to both sides

2x (-4x) - 2 (+2) > 4x (-4x) + 6 (+2)

2x - 4x > 6 + 2

Simplify. Combine like terms

-2x > 8

Isolate the x. Divide -2 from both sides. Note that you are <em>dividing a negative number</em>. When doing so, flip the sign.

-2x/-2 > 8/-2

x > 8/-2

x < -4

x < -4, or (1) is your answer

hope this helps

How are the coordinates of a new point found if the point is reflected through the line y = x? How are the coordinates of the ne
Assoli18 [71]
The a point is refrected through the line y = x, the new point is found by interchanging the x and y-cordinate of the original point. i.e. if the original point is (a, b) and is refrected through the line y = x, the new point will be (b, a).

1) 2x + 8y = 20 what's the solution so confused <br> y = 2
postnew [5]
If y is equal to 2 then you can find x by putting 2 for y so you will have:
2x + 8(2) = 20 
2x + 16 = 20 
2x = 20 - 16
2x = 4 
x = 4/2 
x=2 :)))
