Answer:
x = 50
Step-by-step explanation:
The angles 70, 60, and y are supplementary, meaning that the sum of them is 180. Therefore,
70 + 60 + y = 180 and
y = 50
That means that x = 50 as well, since vertical angles are congruent
Answer:

centre of circle=(-5,3)
put the value of centre and redius in the equation
equation of circle
=4^2
Answer:i think it 3
Step-by-step explanation:
a²+b² = c² where a and b are legs and c is the hypotenuse
So...
a²+4²=13²
a²+16=169
a²=153
a=√153
answer: approx. 12.37 units
