So 0.25 is essentially 25/100. Divide 25 from the top and bottom to get 1/4
-9x=-36
divide both sides by -9
to get x by itself
to get +x
-9x/-9= -36/-9
cross out -9 and -9, then becomes -1*-1*x= x
x= -36/-9
answer:
x= 4

Use the Sine Rule:-
b / sin B = c / sin C
15 / si n B = 9 / sin 29
sin B = 15* sin 29 / 9 = 0.8080
B = 53.90 degrees
The phrase between 7.2 and 7.6 inclusive means:
7.2 ≤ x ≤ 7.6
