4. Priya is teaching her younger cousin to ride a bike. She wants to stay on roads that are not too steep and easy enough for a new bike rider. She has decided the roads must have an angle less than or equal to 7 degrees. A 7 degree angle in a right triangle has a 3 : 25 ratio for the legs. List the legs of 2 right triangles that would be
safe for a new bike rider.​

Respuesta :

Answer:

Having 2 meters and 25 meters legs and 3 meters and 30 meters legs.

Step-by-step explanation:

Priya thinks that an angle of elevation of 7 Degrees or less will be safe for a learner of bike riding.

Now, a 7-degree elevation angle in a right triangle will have a 3 : 25 ratio of its legs.

Therefore, the list of 2 right triangles that would be safe for a new rider will be having 2 meters and 25 meters legs and 3 meters and 30 meters legs.  

I both cases the angle of elevation will be less than 7 degrees. (Answer)

A right angle triangle is a triangle with one of the angle measures of 90 degrees. To maintain this ratio or more than this the legs must be

  • First leg should be -one is 2 meter and other is 25 meters.
  • Second leg should be - one is 3 meter and other is 30 meters.

Given-

Priya thinks that a 7 degrees or less will be safe for the new bike rider.

What is Right angle triangle?

A right angle triangle is a triangle with one of the angle measures of 90 degrees.

A 7 degree angle in a right triangle has a 3 : 25 ratio for the legs.

[tex]\dfrac{3}{25}=k (say)[/tex]

Hence, the legs will be 3k meter and 25 k meter.

If the value of k is 1 then the legs will be 3 meter and 25 meters.

Thus to maintain this ratio two such legs of right triangle has to be find that would be safe for a new bike rider.

To maintain this ratio or more than this the legs must be

  • First leg should be -one is 2 meter and other is 25 meters.
  • Second leg should be - one is 3 meter and other is 30 meters.
