Sansa was explaining the meaning and usefulness of the statement tan 40° ≈ 0. 84. Which true statements below could be part of that explanation? Select all that apply.

o All right triangles with an acute angle of 40° are similar to each other.

o The sum of the squares of the legs of right triangles with a 40° angle equal 40".

o Knowing that tan 40° ≈ 0. 84 is enough information to calculate the sides of any 40°-

50°-90° triangle.

o If you know tan 40° ≈ 0. 84 and the length of the leg opposite to the 40° angle, then

you can calculate the length of the other leg.

o The ratio of the opposite side to the hypotenuse in any right triangle with an angle of

40° is always approximately 0. 84
