Answer: The answer is D
Step-by-step explanation:
Number 3: x+x+100= 180 x=40
number 4: x+x+112=180 x= 34
Consider this option:
1.the equation of the circle using its centre and point (0;-4) is:
x²+y²=4.
2. to substitute given point (23;2) into the equation of the circle:
23²+2²≠4
answer: this point does not belongs to the circle.
