Use a calculator to find the approximate value of sin-1( 0.655).

Radian = 0.7142

Degree = 40.92°

Step-by-step explanation:

Given:

Let,

It is inverse trigonometry function. We have to use calculator to find angle of trigonometry.

The value of y in two form radian or degree

Using calculator to find the value of y

In radian,

In degree,

Hence, The value of in radian 0.7142 and in degree 40.92°

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.
