Mina says triangle A with angles measuring 34° and 57° is similar to

triangle B with angles measuring 57°

and 89º. Is Mina correct?

Yes, Mina is correct

Step-by-step explanation:

Let the triangles be A and B

Given

Triangle A:

Triangle B:

Required

Is Mina's claim correct?

First, we calculate the third angle in both triangles.

For A:

For B:

For triangle A, the angles are: 34, 57 and 89

For triangle B, the angles are: 34, 57 and 89

Since both triangles have the same angles, then by the postulate of AAA (Angle-Angle-Angle), the triangles are similar.

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.

the answer is 21%.
