Answer:
A) 11/36
Step-by-step explanation:
x + 4/9 = 3/4
get a common denominator of 36 (4*9 = 36)
x + 4/9 * 4/4 = 3/4 * 9/9
x + 16/36 = 27/36
subtract 16/36 from each side
x + 16/36 - 16/36 = 27/36 -16/36
x = (27-16)/36
x = 11/ 36

Multiply the one by the 2 and the three by the 2. Put the decimal back in and add the negative sign
The main formula is
sector area = n / 360° x Pi r²
4 = n / 360 x r² = <span>n° / 36,
144° = n</span>
