Jim is designing a seesaw for a children’s park. The seesaw should make an angle of 45 with the ground and the maximum height to which it should rise is 1 meter. What is the maximum length of the seesaw?

B. 1.4 meters

Step-by-step explanation:

From the information given, we can see that a right triangle is formed.

The angle that the seesaw makes with the ground, 45°, is opposite the height to which it should rise.

We are to find the maximum length if the seesaw, which would be the hypotenuse of the right triangle formed.

Use the following trigonometric ratio formula to find the maximum length if the seesaw.

Let x be the maximum length of the seesaw. Thus,

Sin(45) = opposite/hypotenuse

Opposite = 1 m

Hypotenuse = x

Solve for x

Divide both sides by sin(45)
