How many triangles can be drawn with one 90 degrees angle a 70 degrees angle and an included side measuring 3 inches? Explain

Step-by-step explanation:

once we know 2 of the angles we can find a third. once we have all 3 angles we only need one side length to tell us how big it is.

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.
