The interior angles of a triangle have measures (2x−5)° , (4x−1)° , and 30°. what is the value of x?

The value of x is

Step-by-step explanation:

we know that

The sum of the internal angles of a triangle must be equal to

so

solve for x

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.
