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.
