I need help Pls help with both

the first one is 84

Step-by-step explanation:

subtract 145-61 then you get 84for the missing angle.

1. 84,  2. 7.31

Step-by-step explanation:

1. 145-61=84

2. 16x+4-3x+11=110

13x+15=110

13x=95

x=7.31

found it xd it ok yt

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.
