In right triangle ABC, A=28º, b= 7, and ZC is the right angle. Solve the triangle.
OB = 62, a=3.3, C=7.7
B = 62°, a = 7.9, C= 3.7
O B = 62°, a=3.7, C = 7.9
O B= 62°, a=6.2. C= 9.4

B=62, a=3.7, C=7.9

Step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
