Y - 3 = 12 (x - 4)
y - 3 = 12x - 48
y = 12x - 45 is your answer
(edit)
y - 3 = 1/2 (x - 4)
y - 3 = 1/2x - 2
y = 1/2x + 1 is your answer

Answer:
√1924=43.86
Step-by-step explanation:
√(x2-x1)^2+(y2-y1)^2=√1924=43.86
Answer:
R= 20.88 ft
Step-by-step explanation:
See the diagram attached, this satisfies the condition, ΔKLM is enclosed in a circle of radius R.
LN=16 ft (given)
The value of KM is 2R because as the ∠KLM forms an angle of 90°, therefore, the line KM passes through the center.
Area of a triangle =
Now let's find he area of the ΔKLM=
=
Also the area can be found out by =( As KLM is a right angled triangle)
KL= KM cos 25°= 2R cos 25°
LM= KM cos 55°= 2R sin 25°
Area= x 2R cos 25°x 2R sin 25 °
= sin 50°
sin 50°= 16R
R sin 50°=16
R= 20.88 ft
