Given that A, O & B lie on a straight line segment, evaluate acute ∠COD. The diagram is not drawn to scale.

COA 121 COD 47 DOB 12

Step-by-step explanation:

3x+ 88+x+36+2x-10 = to 180 degrees which is the total value of angles on a straight line, thus becoming 6x+114=180 when you put the light terms together it becomes 6x=66 which makes x=11 hence putting x to required places resulting to the answer above

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.

step-by-step explanation:

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
