a. I agree because ΔVWS is a 180° rotation of ΔXWV, and the points match up.
b. It is a SAS congruence postulate and it's just a 180° rotation and the points match up.
That's what i put I don't know if its correct
Answer:
One Solution
Step-by-step explanation:
x + 3y = 3
x - y = -3
4y = 6 Subtract to solve by elimination.
y = Divide by 4.
x - = -3 Substitute for y in the original equation.
x = - Add .
Circumference is 40 in and area is 150 in²
Step-by-step explanation:
- Step 1: Find the circumference of the circle when radius = 7 in
Circumference = 2πr = 2 × 22/7 × 7 = 44 in ≈ 40 in
- Step 2: Find the area of the circle.
Area = πr² = 22/7 × 7² = 154 in² ≈ 150 in²
