Answer:
12 sides and measure of each interior angle is 150...
Answer:
y=2x+y-int
Step-by-step explanation:
If the line is parallet to the defined by the given equation the slope of the unknown line is m=2.
Use this value of slope to calculate the y intercept. 2 = ( 2 - y-int)/4 - 0)
THus, your equation is y = 2x + y-int
This will be easier to write, and a lot easier to read, if we temporarily
use another symbol ... say, 'Q' ... to represent ' sin(2x) ' .
Here we go:
Original equation: Q² - 0.5 Q = 0
Factor the left side: Q (Q - 0.5) = 0
This equation is true if either factor is zero:
-- If Q=0, then sin(2x) = 0
2x = 0°, 180°, 360°
x = 0°, 90°, 180°
-- If (Q-0.5) = 0, then Q = 0.5
sin(2x) = 0.5
2x = 30°, 150°
x = 15°, 75°
The whole collection of solutions
between 0° and 360° :
x = 0°, 15°, 75°, 90°, 180° .
Answer:
Using properties of parallelogram and angle sum property of a triangle in the figure as shown below in the attachment
In parallelogram ABCD, AC is a diagonal.
Given: 
and 
As, we know that opposite angles in parallelogram are equal.
therefore,
Now, in ΔADC
Sum of the measures of angles in a triangle is 180 degree.
Substituting the values of 
and we have;
or
Subtract 
from both sides we get
Therefore, the measure of angle CAD is 
.
