Question

At Castle Trigon, they are trying to determine how far the catapult is away from the tower at point A. Two soldiers using angle measuring devices determined that the angle at point B was 80° and that the angle at point A was 70°. If the two soldier stationed at points A and B are exatly 110 feet away from each other, how far is it from the catapult (point C) to the Tower at Point A?

    Answer:

    216.7

    Step-by-step explanation:

    Use the Law of Sine Formula:

    a/SinA = b/SinB = c/SinC

    You are looking for side “b” in this case

    Add up the Angles first so you can get Angle C:

    180 – (80+70) = 30

    After you get that, you have all your needed information to find “b”:

    b/Sin80 = 110/Sin30

    Cross multiply and you will get:

    b . Sin30 = 110 . Sin80

    b = (110 . Sin80)/Sin30

    Enter that into your calculator and you will get “216.7”
