Answer:
see explanation
Step-by-step explanation:
We require to find the slope m of the line joining the 2 given points
To find m use the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2,3) and (x₂, y₂ ) = (1, - 2)
m = = = 5
Given a line with slope m then the slope of a line perpendicular to it is
= - = -
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept ), thus
y = - x + c ← is the partial equation of the perpendicular line
To find c substitute (- 3, 2) into the partial equation
2 = + c ⇒ c =
y = - x + ← perpendicular equation
Sin is opposite over hypotenuse. The opposite is 12 in this case, and the hypotenuse 13. The answer is 12/13.
Answer:
B
Step-by-step explanation:
Divide 168 by 2 to get 84, then divide 168 by 84 to get 2, now we can divide 231 by 84 to get our answer B.
