Question 1121139: In a game of soccer, a goal kicker is to attempt a penalty goal. The ball is placed 28 metres from one upright and 26m from the other. The goal posts are 4m part. Within what angle mist the player kick the ball to score a goal? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Draw the triangle.
Side a is 28, side b is 26 and side c, the goal is 4
Find the angle.
c^2=a^2+b^2-2ab cos C
substitute in the Law of Cosines
16=784+676-2*728 cos C
-1456 cos C=-1444
cos C=-1444/-1456=0.9918
angle is 7.36 degrees.
