General formula of the circle
(x-a)² + (y - b)² = r²,
where (a,b) - coordinates of the center, r - radius of the circle.
(x-3)²+(y+4)²=4
(x-3)²+(y+4)²=2²
So, the center is (3, -4) and radius r = 2.
A. (3, –4); 2
B. a parallelogram with four congruent sides
Answer:
90°
Step-by-step explanation:
Interior angles of ALL triangles sum to 180°
The whole large triangle has angles 60 60 60 ( they sum to 180)
that means x = 30
then the small triangle on the right has 60 + 30 + y = 180
meaning y = 90 °
Answer is D
Step by step explanation
Answer:
The answer would be 3.
Step-by-step explanation:
This can be found by subtracting 12 from both sides and then the x will be alone on one side and be set equal to 3 on the other side.
