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.

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

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

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.

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

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)

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

x = 23.78
