Tell whether the triangle is a right triangle 14.2 19.8 22.9

No it is not

Step-by-step explanation:

       +1+1

          19.8

     +   14.2                   *It's supposed to be 90 degrees for a right triangle.*

          *for this it's only 34 degrees. So the answer is

       =  34.0                                                      no*

e) none of the above because the measure of angle cba is 101°

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
