lines cd and de are tangent to circle a shown below:

lines cd and de are tangent to circle a and intersect at point d. arc ce measures 98 degrees. point b lies on circle a.

if arc ce is 98°, what is the measure of ∠cde?

56°
49°
131°
82°

82°

Step-by-step explanation:

whenever a line is tangent to a circle, the line segment you can draw from the center to the tangent line on the circumference is always perpendicular, so angle ACD is 90° and angle AED is 90° and we already know CAE is 98° so adding the tree would result in 278° because ACDE forms a quadrilateral it's angle have a sum of 360° so subtract 278 from 360 and you get 82°

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

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.
