Point P(5,0) is on the terminal arm of an angle k in standard position.
7nadin3 [17]

The value of the cosine of angle k is 1.

Given a point (x,y) that is a terminal arm of an angle k in standard position, by trigonometric relations we have the following expression for the cosine:

\cos k = \frac{x}{\sqrt{x^{2}+y^{2}}} (1)

Where:

  • k - Angle measure, in sexagesimal degrees.
  • x - Horizontal position of the point of the terminal arm, no unit.
  • y - Vertical position of the point of the terminal arm, no unit.

If we know that x = 5 and y = 0, then the cosine of the angle k is:

\cos k = \frac{5}{\sqrt{5^{2}+0^{2}}}

\cos k = 1

The value of the cosine of angle k is 1.

1 day = 1500 bricks

5 days = 1500 x 5 
5 days = 7500 bricks

Answer (a) He would expect to lay 7500 bricks in a five day week.

1500 bricks = 8 hours
1 brick = 8/1500
10 000 = 8/1500 x 10 000 = 53 hours (nearest hour)

Answer: (b) It will take him 53 hours to lay 10000 bricks.
