Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 for B
B = 180° - (90 + 39)° = 180° - 129° = 51°
Using the tangent and sine ratios in the right triangle for b and c
tan39° =
= 
Multiply both sides by b
b × tan39° = 27 ( divide both sides by tan39° )
b =
≈ 7.5 ( to the nearest tenth )
sin39° =
= 
Multiply both sides by c
c × sin39° = 27 ( divide both sides by sin39° )
c =
≈ 28.0 ( to the nearest tenth )
121 should be the correct answer

Answer:
let say the number is x, then 30x÷100=78, x=260...from this we can calculate 95 percent of 260 which is equal to 247
