The answer is 80
The two triangles are the same.
Corresponding angles of congruent triangles are equal.
A triangle's three angles add up to 180 degrees.
Answer:
Equation: (x+9)² + (y+2)² = 100
4 points: (1, -2) (-1, 4), (-3, -10) (-19, -2)
(-3, 6) is on the circle
Step-by-step explanation:
(h, k) (-9, -2)
Equation: (x+9)² + (y+2)² = 100
4 points: (1, -2) (-1, 4), (-3, -10) (-19, -2)
(-3, 6) is on the circle
check: (-3 + 9)² + (6 + 2)² = 36 + 64 = 100 = 10²
Answer:
-The result for the midpoint:

Step-by-step explanation:
-To find the midpoint, you need this formula:

-Next, the two points (7,7) and (0,-3) for the formula:

-Then, you solve it:



-So, therefore, the answer is
.
I’m sorry but your spelling prohibits me from answering correctly
Multiply x and y by 1/2(0.5)
-8 × 1/2 = -4
-2 × 1/2 = -1
Answer: B'(-4, -1)
