    Given: <RST ~ <WSU Prove: m<RSW = m<TSU

    Given: <RST ~ <WSU Prove: m<RSW = m<TSU <RST < WSU. (Given) <RSW = <RST + <TSW (Angle Addition Postulate) <TSU = <TSW + <WSU (Angle Addition Postulate) Since <RST = <WSU (Given), we have: <RSW = <WSU + <TSW Therefore, <RSW = <TSU

    triangle sum theorem

    The triangle sum theorem states the sum of the three angles in a triangle equals 180 degrees. So if you're given two angles and need too find the 3rd angle, add the 2 known angles up, and subtract them from 180 to get the 3rd angle measure.

    There is an escalator that is 1090.3 feet long and drops a vertical distance of 193.4 feet. What is

    There is an escalator that is 1090.3 feet long and drops a vertical distance of 193.4 feet. What is its angle of depression? The sin of the angle A is the length of the opposite side / hypotenuse. sin(A) = Opposite / Hypotenuse sin(A) = 193.4 / 1090/3 sin(A) = 0.1774 We want the...
