An isosceles triangle has base angles that each measure 52º. Which equation can be used to find z, the measure of the third angle of the isosceles triangle in degrees?
A. 104 + 2z = 180
B. 104 + z = 180
C. 52 + 2z = 180
D. 52 + z = 180

I'm not the best at this but the answer that makes the most sense is B. 104+z=180

Step-by-step explanation: A triangle has 2 sides which are both 52 degrees. Add those to get 104 degrees. Now since a triangle has 3 sides we need to find the one other side so no answers with 2z match meaning the answer should be B.

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

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.
