Ts option A
cos C = (b - x) / a
a cos C = b - x
x = b - a cosC
Answer:
d) 3x + y = 5
Step-by-step explanation:
The standard equation of a line with slope and a point is given by:
y = mx + b
We know that
m=-3
Putting the value of slope
y = -3x+b
To find the value of b, we will put the point in the equation
-1 = (-3)(2)+b
-1 = -6 + b
-1+6 = b
b = 5
Putting the values of b and m in standard equation
y = -3x+5
Can also be written as:
3x+y = 5
Hence,
Option d: 3x + y = 5 is the correct answer ..
Hello,
The length of the line segment is the distance betheen the 2 points
d²=(3-6)²+(1-6)²=9+25=34 (pythagorean theorem)
d=√34
