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.
A)All right triangles with an acute angle of 40° are similar to each other.
B)The sum of the squares of the legs of right triangles with a 40° angle equal 40^2
C) Knowing that tan 40° -0.84 is enough information to calculate the sides of any 40°-50°-90° triangle
D)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.
E)The ratio of the opposite side to the hypotenuse in any right triangle with an angle of 40° is always approximately 0.84.
