I need help with this ASAP

n = -9/2 = - 4 1/2

Step-by-step explanation:

-11 - 2 1/4n = -7/8

-9/4n = -7/8 + 11

-9/4n = 88/8 - 7/8

-9/4n = 81/8

n = 81/8(-4/9)

n = 9/2(-1)

n = -9/2 = - 4 1/2

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
