if you add 2 sides of a triangle the other must be smaller and if you subtract 2 sides the other must be greater
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
b: |12 – x| ≤ 0.25
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.
