Answer:
x= 20
Step-by-step explanation:
a flat angle is, in terms of geometry, the space between an intersection between two lines whose opening measures 180 degrees or 180º. Since the angle is 180º there is no difference between two lines or a line and we can say that the angles in a straight line always add up to 180º.
Step 1
define
according to the graph
3x+80+2x=flat angle=180°
3x+80+2x=180°
Step 2
solve for x
3x+80+2x=180°
5x+80=180
subtract 80 in each side
5x+80-80=180-80
5x=100
divide by 5
(5x)/5=100/5
x=20
happy to help:)
The problem gives you the values of X. This allows you to figure out what y is.
SO lets do it :)))
4y-2(0)
4y-0=0
4y=0
divide 4 from each side
y=0
SO first line is
X Y
0 0
Keep doing them for each equation.
If the X's and Y's have a linear pattern with each other. They are linear lines
:))) Hope this helps. If you need help message me. :)))))))
Using the circle theorems, the value of z is 45
<h3>Circle Geometry </h3>
From the question, we are to determine the value of z
From the given information,
KM is a diameter
∴ ∠KLM = 90° (<em>Angle in a semicircle</em>)
Also, ΔKLM is isosceles
∴ ∠KML = ∠MKL (<em>Base angles of an isosceles triangle</em>)
Then,
∠KML + ∠MKL + ∠KLM = 180° (<em>Sum of angles in a triangle</em>)
2× ∠KML + 90° = 180°
2× ∠KML = 180° - 90°
2× ∠KML = 90°
∠KML = 90°/2
∠KML = 45°
Now, we can observe that
z° = ∠KML (<em>Angles in alternate segment</em>)
But,
∠KML = 45°
∴ z = 45
Hence, the value of z is 45
