Answer:
3n+2(n+2)=9n+12
3n+ 2n + 4 = 9n + 12
3n+ 2n +4 - 4 = 9n + 12 - 4
3n + 2n - 9n = 12 - 4
5n - 9n = 8
<u>-4n </u> = <u>8</u>
-4. -4
n. = - 2
The hypotenuse MO is found from the Pythagorean theorem to be
MO = √(12² + 5²) = √(144+25) = √169 = 13
The sine of angle O is the ratio of the opposite side (MN=12) to the hypotenuse (MO=13). The appropriate choice is ...
C. 12/13
