Actually Welcome to the Concept of the Trigonometry.
here, we use the Linear pair property of the adjacent angles.
We know that, all the adjacent angles in a linear pair add to get 180°
so we get as,
=> (n+6) +90°+(2n+3) =180°
=> (n+6) +(2n+3) =180-90
=> 3n+9 = 90
=> 3n= 90-9
=> 3n = 81
hence, n = 81/3
=> n = 27°
thus the value of n is 27° .
800 px - 600 px
1,260 px - x px
1,260 px - x px
You would select the points with the x-values -3 and 2 and use the slope formula:
(-3, -36) and (2,4)
← slope formula
x1 = -3 y1 = -36 and x2 = 2 y2 = 4
(-3, -36) and (2,4)
x1 = -3 y1 = -36 and x2 = 2 y2 = 4
