Answer:
10
Step-by-step explanation:
one interior angle in a pentagon is 108^o.
5 interior angles are 540^o.
If we add 12+7+16+9+10, we get 54x=540^o
That means x=10
Answer:
(x + 1)² + (y - 3)² = 8
Step-by-step explanation:
radius (r): √(1 - (-1))² + (1 - 3)² = √8 = 2√2
Formula for circle with center (h,k): (x – h)² + (y – k)² = r²
(x + 1)² + (y - 3)² = 8
