a.
To find larger angle out of
a.
Answer to Problem 13WE
Angle A is larger
Explanation of Solution
Given information:
Given diagram shows a goalpost.
Distance of B from in front of right pole is 40 foot.
Distance of A from the center of goal is 40 feet.
Width of goal is 24 feet.
To find the angles of A and B, trigonometric ratios can be applied in the small
Calculation:
Hence, angle B will be less than
For angle A another triangle can be formed as
Here,
By comparing tangent of angles formed by A and B it can be said that angle A is larger than B.
Conclusion:
Therefore, Angle A turns out to be larger than B by the use of trigonometric functions.
b.
To find the point from where there will be more chances of kicking the ball into goal.
b.
Answer to Problem 13WE
From point A
Explanation of Solution
Given information:
While kicking a ball into goal, a player must have a wider view to increase the chances of scoring.
As found out in the previous result that angle A is larger than B, the player at point A will have wider view of the goal as compared to B.
So, there will be more chances of kicking the ball into the goal from point A.
Conclusion:
Therefore, player at point A will have a higher chance of kicking the ball into goal because of a wider view of goal as compared to point B.
