Basically use the formula y1-y2 over x1-x2 and just plug in the number
Answer: 18
Step-by-step explanation:
By the angle bisector theorem, 
Answer:
Step-by-step explanation:
-5x-4y=-4 ...(1)
25x+ 20y = 20 ....(2)
multiply (1) by -5 you have : 25x+ 20y = 20 ....(2) same equation , same line
so : The system has infinitely solutions.
Answer:
The relationship between the arc length (S), the radius (r), and the angle subtended by the arc at the center (theta), is given by the formula S = r(theta), when theta is in radians. And is given by ((theta)/360) x 2pi r, when theta is in degrees.
