Referring to the figure, find the sine of angle R. Reduce the answer to the lowest terms. Okay so i have literally no idea how to do this so if someone could just explain it to me

    with respect to angle R, the opposite side is TS |dw:1440467702221:dw|

    the adjacent side is RT |dw:1440467734346:dw|

    and the hypotenuse is RS the hypotenuse is always the longest side of a right triangle it is always opposite the right angle |dw:1440467770507:dw|

    now use SOH CAH TOA the SOH refers to S = sine O = opposite H = hypotenuse basically sine(angle) = opposite/hypotenuse

    hopefully this sounds familiar from your lesson?

    do you see how I set up the opposite, adjacent and hypotenuse in the drawing?

    Yes that makes sense

    so sin(R) = opposite/hypotenuse = TS/RS = 8/10 = 4/5
