MATH HELP!!!

Given a right triangle with a side of length 4 and a hypotenuse of length 7, find the measure of the two acute angles. (Round to the nearest hundredth.)

  • trigonometry -

    One side length of a right triangle is 4 and the hypotenuse is 7.
    Then
    sin(θ)=4/7, and
    θ = sin-14/7.
    (you will need to use the calculator for finding θ).
    Similarly, the other angle can be calculated from:
    φ = 90°-θ

    thank you so much.. it really helped but i have one more,

    The hypotenuse of a right triangle is 5 inches. If one leg is 2 inches, find the degree measure of each angle.

    A. 42.4° and 47.6° B.12.2° and 77.8°
    C. 23.6° and 66.4° D.16.7° and 73.2°

    This is almost the same problem as the previous.

    One side length of a right triangle is 2 and the hypotenuse is 5.
    Then
    sin(θ)=2/5, and
    θ = sin-12/5.
    (you will need to use the calculator for finding θ).
    Similarly, the other angle can be calculated from:
    φ = 90°-θ
