Answer:
The value of x is 90°
Step-by-step explanation:
Given as :
The Trigonometrical equation as :
sin² x - 2 sin x + 1 = 0
Now, Let Sin x= a
So, The equation can be written as :
a² - 2 a + 1 = 0
<u>applying mid-term break</u>
a² - a - a + 1 = 0
Or, a ( a - 1) - 1 (a - 1) = 0
Or, (a -1) (a-1) = 0
∴ a - 1 = 0
i.e a = 1
Now, put the value of a
∵ Sin x = a
So, Sin x = 1
∴ x =
Or, x = 90°
So, The value of x = 90°
Hence, The value of x is 90° Answer
Simple, use the process of elimination to figure this out:
4x-y=2
2x+9y=-12
Convert these, to be able to find either x or y.
2(4x-y=2) 8x-2y=4 multiply by 2.
then
4(2x+9y=-12) 8x+36y=-48
Which makes them
8x-2y=4
-
8x+36y=-48
-38y=52
This simplified makes it y= -26/19.
Then plug y back into the original equation
4x-y=2
4x-(-26/19)=2
Making it x= 3/19.
Thus your Point of Intersection is at (3/19, -26/19)
