Answer:
-1/5
Step-by-step explanation:
: )
The equation of a cricle is

h being the x coordinate of the given point and k being the y coordinate of the given point (r also being the radius).
Now we have to plug the points into the equation

now just simplify the the equation
Answer:
Step-by-step explanation:
supplementary angles sum = 180
Measurement of Measure of its
an angle Supplement
80° 180 - 80 = 100°
25° 180 - 25 = 155°
119° 180 - 119 = 61°
x 180 - x
To estimate an answer to this problem, you must first estimate the numbers as well. 189 would round to 190, and 643 would round to 640. Now you would subtract 190 from 640, giving you 460.
Answer:
x=18
Step-by-step explanation:
We'll assume that the shorter sides are AB and CD. Then 7x-6=5x+30. You add 6 to both sides. 7x=5x+36. Isolate x. 2x=36. Divide, and x=18.
